Causes of back pain: conditions that require ultrasound

Back pain is a common problem in modern people, attributed to poor posture, muscle tension, and overexertion. However, if the pain persists, recurs, or is accompanied by other symptoms, it may not just be a musculoskeletal problem, but a warning sign from the body's deep organs. In this caseIt has become an important non-invasive diagnostic tool. Ultrasound uses high-frequency sound waves to penetrate human tissues, forming real-time images and effectively detecting internal structural abnormalities that are invisible to the naked eye.

What are the symptoms of back pain that require ultrasound? First, if the pain is fixed on both sides of the lower back or upper back and is related to eating or urination, it may suggest kidney or gallbladder problems. For example, pain from kidney stones or kidney infections often radiates to the back. Second, if the pain includes unexplained fever, weight loss, or a lump in the abdomen, it is important to pay attention to lesions in the abdominal organs such as the liver, pancreas, and spleen. In addition, people with long-term hepatitis B and C or fatty liver may be recommended by their doctor for regular treatment even if the symptoms are not obviousTo monitor liver health and rule out the possibility of cirrhosis or tumors. Finally, if the pain is caused by certain joints or soft tissues and is accompanied by redness, swelling, and limited range of motion, musculoskeletal ultrasound can clearly show damage, inflammation, and fluid accumulation in tendons, ligaments, bursa, etc. Therefore, if back pain exceeds the scope of a common burden injury and is especially comorbid with medical symptoms, actively discussing the need for ultrasound with your doctor is an important step to clarify the cause and avoid delays in treatment.

Related ultrasound examination items provided by public hospitals

The public hospital system (HA hospital) in Hong Kong offers targeted ultrasound examinations to address various underlying conditions that may result from low back pain. These examinations are performed by experts in radiology and related specialties, aiming to provide accurate diagnostic images. Common related items mainly include the following categories:

公立醫院照超聲波

• Renal ultrasound:It is the first choice to check if back pain is due to urinary tract problems. It can clearly determine the size, shape and location of both kidneys, and also check for the presence of stones, cysts, hydrocele (dilated renal pelvis), tumors and structural abnormalities. It is especially important for patients with recurrent back pain, hematuria, and urinary tract infections.
• Abdominal ultrasound (entire abdomen or upper abdomen):The examination covers the liver, gallbladder, bile ducts, pancreas, spleen, and large blood vessels (e.g. abdominal aorta). For example, gallstones can cause pain in the upper right abdomen or back. Pancreatitis and pancreatic tumors can also cause severe back pain. Abdominal aortic aneurysms are also one of the causes of life-threatening back pain. Among themLiver ultrasoundIt is an important tool for the assessment of liver parenchyma and the detection of fatty liver, cirrhosis, liver cysts, and liver tumors.
• Musculoskeletal ultrasound:It is specifically designed to check for soft tissue problems. For back pain caused by sports injuries, repetitive strains or degeneration, it is possible to diagnose muscle tears, tendonitis, ligament injuries or arthronephritis with a detailed assessment of the condition of the psoas, fascia and facet joints of the spine, as well as the hip and sacroiliac joints.

The main purpose of these tests is to help doctors diagnose the underlying diseases and structural problems behind pain, such as stones, inflammation, infections, cysts, tumors, and vascular lesions, through safe and non-radiation-free imaging methods, and to provide a solid basis for future treatment plans. From the method of selectionThis allows test results to be integrated directly into the patient's public medical record, making it easier for multidisciplinary teams to follow up.

Billing standards for various ultrasound examinations

The fees for ultrasound examinations in public hospitals in Hong Kong are mainly divided into two categories: "eligible persons" (residents with Hong Kong identity cards) and "ineligible persons", which are uniformly carried out according to the fee structure of HA. The fees for eligible people are very subsidized as public medical services and are much lower than those in the private market. The following are some of the common ultrasound examinations related to low back painOverview (data as of 2023, reference only, actual fees are subject to the latest announcement of the hospital):

It is important to note that the above fees only apply to the test itself. Patients are typically diagnosed by a general or specialized outpatient physician at a public hospital and then referred for consultation. The outpatient consultation fee ($80 per session) and subsequent medications and treatments are paid separately. Additionally, the waiting time varies depending on the hospital, department, and the urgency of the symptoms, and can range from several weeks to several months. Still, compared to private tests, which can cost several thousand dollars, public hospital fees provide affordable and high-quality diagnostic options for the general public.

How to ask a doctor for an ultrasound

In the public health system, it is necessary to use testing resources reasonably, and cannot be immediately requested by patients. Successfully referred for treatmentUltrasound examination in public hospitalsThe key is to communicate effectively with your doctor and provide sufficient clinical evidence. FirstDescribe your symptoms in detailIt is very important. Don't just say "back pain", be specific: the exact location of the pain (e.g., left lower back, middle hip), the nature of the pain (tingling, dull pain, colic), the time and frequency of attacks (persistent, intermittent, intensifying at night), the level of pain (rated on a scale of 1 to 10), and the aggravating or mitigating factors of leaning forward, coughing and eating after eating. More importantly, it is essential to know all the accompanying symptoms, such as fever, chills, pain and blood in the urine, unexplained weight loss, jaundice (jaundice) on the skin and in the white of the eyes, and weakness or numbness in the lower extremities. These details can help you associate the pain with a specific organ system.

Next, the criteria for doctors to determine whether examination is necessary are mainly based on clinical evaluation and diagnostic guidelines. The doctor will perform a physical examination, such as blowing pain around the kidneys, palpation of tenderness or lumps in the abdomen, and examination of nerve reflexes. Patient's age and medical history (e.g., kidney stones, hepatitis, history of cancer, family history, initial examination findings, etc.). If the doctor determines that the pain is likely to be a simple musculoskeletal problem, conservative treatment (e.g., rest, physiotherapy) may be recommended first. However, if "warning signs" are found, such as severe post-traumatic pain, neurological symptoms, suspected infection, cancer risk factors, etc., the doctor will issue a more detailed referral and arrange corresponding ultrasound and other imaging tests. Therefore, instead of directly "asking for a consultation", it is preferable to provide a complete and clear medical history to help the doctor make the most professional clinical judgment, which can naturally guide the necessary examination procedures.

Ultrasonic Inspection Process

If the doctor deems it necessary and prescribes a referral, the patient will be hospitalizedPublic HospitalsAnd then there is the formal inspection process. The whole process usually includes the following steps:

How to make a reservation and what information you need

Medical staff will assist the patient with their appointment. Patients should bring a referral letter, identity document (e.g., Hong Kong Identity Card), and relevant medical records or imaging reports (if any). At the time of the appointment, they will be informed of the date, time, and location of the examination (usually the diagnostic radiology department of the hospital), as well as instructions on preparing for the pre-examination and any fees to be paid.

Preparation before the exam

Preparation depends on the type of exam:
Ultrasound of the kidneys or abdomen:Patients are usually asked to fast for 6-8 hours before the examination, which is done to reduce the interference of intestinal gases and make organs such as the liver, gallbladder, pancreas, and kidneys look clearer. Sometimes, it is necessary to drink the right amount of water and hold urine to fill the bladder for observation of the pelvic organs and evaluation of the ends of the ureters.
Musculoskeletal ultrasound:Generally, there is no special preparation, and loose clothing should be worn to make it easier to expose the test area. Avoid applying lotion or ointment to the test area.

Inspection process and report collection

On the day of the examination, you will arrive at the radiology department on time to register and pay. Once in the examination room, the radiographer or radiologist will lie down on the examination table and instruct you to apply the clear gel to the skin (this helps conduct sound waves). The probe will trace the affected area and you may be asked to change position or temporarily hold your breath to get the best image. The procedure is painless, does not involve radiation, and usually takes 15 to 30 minutes. After completion, the gel can be easily wiped off. The images will be analyzed by the radiologist and an official report will be produced. The report will not be provided on the spot and will usually be returned to the specialist outpatient you referred to. At your next follow-up, your doctor will explain the results and follow-up arrangements. OverallUltrasound examination in public hospitalsThis process emphasizes systematization and specialization, ensuring accurate and consistent diagnoses.

Interpretation of ultrasound results

Once the ultrasound results are obtained, the most important steps are interpreted by the family doctor. The doctor interprets the importance of diagnostic imaging based on clinical signs and symptoms. The report usually includes a description of the organ being examined: whether the size, morphology, boundaries, internal echo (texture) are uniform, and the presence or absence of abnormal lesions such as stones, cysts, lumps or secretions. For instanceLiver ultrasoundThe report may state that "enhanced liver echo, suggesting fatty liver" or "hypoechoic nodules in the liver parenchyma, recommending further examination".

When interpreting the report, the doctor clearly communicates normal age-related changes (e.g., simple kidney cysts), benign problems (e.g., cholesterol polyps), and anything that requires attention or immediate follow-up. If a clear cause, such as a kidney stone or tendon rupture, is directly discussed for treatment options such as medication, physical therapy, or surgery. If unclear or suspicious lesions are found, other tests such as computed tomography (CT), magnetic resonance imaging (MRI), or tissue removal (biopsy) may be recommended to confirm the diagnosis. Follow-up treatments and recommendations depend entirely on the diagnosis. Regular follow-up monitoring (e.g., stable fatty liver) or detailed treatment with appropriate surgery or referral to a specialist may be possible. It is important to rely on the doctor's professional judgment as the ultrasound report is a professional medical document and can lead to misunderstandings and concerns if interpreted on your own.

What other tests can diagnose back pain besides ultrasound?

Ultrasound is a powerful tool, but not a panacea. Diagnosis of back pain requires a variety of complementary tests. The doctor will choose the most appropriate test based on the suspected cause.

• X-ray examination:The most basic imaging tests can quickly check the skeletal structure of the spine and diagnose fractures, spondylolisthesis, severe joint degeneration, and scoliosis. However, information about soft tissues, discs, and nerves is limited.
• Computed tomography (CT):X-rays are taken from multiple angles to synthesize cross-sectional images. Visualization of bone details, complex fractures, and specific visceral problems (e.g., complex kidney stones, abdominal tumors) is superior to ultrasound. Ultrasound is often used to assess pre-traumatic and scheduled surgery.
• Magnetic resonance imaging (MRI):It does not contain radiation and uses magnetic fields and radio waves for diagnostic imaging. It has a very high resolution on soft tissues and is considered the "gold standard" in the evaluation of herniated discs, spinal cord compression, radiculopathy, spinal infections, and tumors. This is especially important when low back pain accompanied by numbness or muscle weakness in the legs is suspected to be nerve compression.
• Bone scan:By injecting a small amount of radioactive tracer, it detects active bone metabolism areas. It also helps detect occult fractures, bone infections, and cancer metastases that are difficult to detect with X-rays.
• Blood and urine tests:It is not a diagnostic imaging test, but it is an essential test. It detects inflammatory indices, kidney function, liver enzymes, electrolytes, uric acid, etc., and is useful in diagnosing infections, autoimmune diseases (such as ankylosing spondylitis), kidney disease, and metabolic bone diseases.

Which test to choose depends on the doctor's initial decision. SometimesPublic hospital ultrasound feesIt is inexpensive and does not contain radiation, making it the preferred tool for screening. If the results of the ultrasound examination are unclear or complex problems are found, the doctor will arrange additional tests such as CT or MRI step by step to create a complete diagnostic image.

Health tips for preventing back pain

As we explore various tests, proactive prevention is best to treat the root cause. Here are some practical and evidence-based health tips to reduce the occurrence of back pain.

1. Strengthens the core muscles:The core muscles of the abdomen and lower back act like natural lower back protection. Regular workouts such as planks, bridge poses, and bird and dog poses help stabilize the spine and reduce strain on the lumbar spine.
2. Maintain proper posture:Keep your spine neutral when sitting, standing, walking, or lifting heavy objects. Avoid using your phone or slouching for long periods of time. Use ergonomically appropriate chairs and equipment and try to stand up and move regularly.
3. Maintain a healthy weight:Being overweight or obese can increase pressure on the lumbar spine and lower extremity joints, accelerating degeneration. A combination of a balanced diet and regular exercise is key to weight management.
4. Safe Handling Tips:When lifting objects, bend your knees, keep your spine straight, engage your leg muscles, and don't bend down to lift heavy objects directly.
5. How to choose the right mattress and pillow:The mattress should be moderately soft and firm, and should be able to support the curve of the spine. The height of the pillow should maintain the natural curve of the cervical spine.
6. Do low-impact exercise regularly:Exercises such as swimming, trotting, cycling, yoga, and tai chi improve overall flexibility, strength, and circulation with little effect on joints.
7. Stress Management and Ensuring Adequate Sleep:Long-term stress can cause muscles to stiffen involuntarily, causing pain. Learn relaxation techniques and ensure quality sleep to give your body time to recover.
8. Regular Health Check-ups:If you have a history of hepatitis or risk factors such as kidney stones, you should follow your doctor's instructions for regular checkups, even if you have no obvious symptomsLiver ultrasoundThis is to catch potential problems early.

Prevention is better than cure, and incorporating these habits into your daily routine can effectively reduce back pain and improve your quality of life.

「」網路廣告滿天飛，如何辨別合法與高利貸？

你是否也有過這樣的經驗？滑手機時，螢幕角落突然跳出「急用錢？免審核、三分鐘放款」、「，今日申請今日拿」這類斗大的廣告標語。無論是社群媒體、新聞網站，甚至通訊軟體的聊天群組裡，這類聲稱能快速解決資金需求的訊息幾乎無孔不入。對於手頭正緊、需要一筆小額款項周轉的人來說，這些廣告無疑充滿了誘惑力，彷彿是即時的救命稻草。然而，在這片看似便利的網路借貸叢林中，實際上潛藏著許多不為人知的風險與陷阱。許多打著「急借一萬」名號的業者，可能並非合法的金融機構，而是遊走於法律邊緣，甚至根本就是違法的高利貸集團。今天，我們就來深入聊聊，當你需要時，該如何睜大眼睛，從滿天飛的廣告中，分辨出誰是正派經營，誰又是可能讓你陷入債務深淵的剝削者。

合法借貸 vs. 非法高利貸：法律告訴你界線在哪裡

首先，我們必須建立一個基本觀念：不是所有民間借貸都是非法的，但超過法律紅線的就是「重利罪」，也就是我們俗稱的高利貸。根據中華民國《民法》第205條規定，約定利率超過週年百分之十六者，超過部分的利息，債務人可以拒絕給付。這是第一個重要的法定利率上限。然而，更嚴格的標準來自《刑法》第344條重利罪，它雖然沒有明確寫出數字，但實務上法院判決會綜合考量：約定的利率是否「顯不相當」、業者是否利用借款人急迫、輕率或無經驗的處境。簡單來說，如果你因為而慌不擇路，對方趁機要求遠高於市場行情（例如月息超過20%，換算年息超過240%）的利息，並搭配苛刻的還款條件，就可能構成重利罪。合法的借貸機構，無論是銀行、信用合作社，還是受政府嚴格監管的合法融資公司，其利率、費用都必須公開透明，並且絕對遵守法律規定。他們賺取的是合理的利息差價，而非利用你的困境進行掠奪。了解這條法律界線，是你保護自己的第一道防火牆。

五個實用技巧，一眼看穿高利貸偽裝

知道了法律定義，但在實際面對那些花言巧語的廣告或業務時，該如何具體判斷呢？以下提供五個清晰可操作的辨別技巧，請務必記在心中。

1. 第一招：嚴檢利率與總費用，是否超過法定天花板？

    

   這是核心中的核心。任何借貸前，務必問清楚「總費用年百分率（APR）」。APR包含了利息加上所有相關費用（如手續費、服務費等），能真實反映成本。如果對方閃爍其詞，只說「月息很低」、「一天只收一點點」，你就要高度警覺。請直接要求換算成年利率。記住，民法16%是一條線，而通常年利率超過30%就已極具風險。舉例來說，若你急借一萬，對方說十天後還一萬兩千元，這十天的利息是兩千元，換算年利率高得驚人，這絕對是不合法的。

    

2. 第二招：查證是否有實體營業據點與合法登記？

    

   合法的金融機構一定能在經濟部商業司的商工登記公示系統，或金管會的相關網站上查到公司登記資訊。他們通常也有實體的營業據點，而非只有一個LINE ID或網路表單。在決定前，不妨親自或請朋友到該公司地址看看，是否確實有掛牌營運。高利貸業者則多隱身在網路背後，或用假地址，一旦出事根本求償無門。一個連公司門面都不願讓你看清的業者，你敢把個人資料和財務安全交給它嗎？

    

3. 第三招：合約是否透明、清楚，並提供審閱期？

    

   「簽約」是關鍵步驟。合法業者會提供一式兩份、條文清晰完整的書面契約，裡面會載明借款金額、利率計算方式、還款期數、每期應還金額、所有費用項目，以及違約的處理方式。根據消費者保護法，你通常有至少三天的契約審閱期，可以帶回家仔細看，甚至諮詢法律專業人士。反之，非法業者常使用模糊不清的合約，或急著要你當場簽名、按手印，不讓你有時間思考，這其中往往藏有對你極度不利的條款。

    

4. 第四招：是否要求抵押身分證、健保卡或存摺「正本」？

    

   這是一個非常危險的紅旗！正規的借貸管道在進行身分驗證時，頂多要求「核對」證件正本，或收取「影本」，絕不會扣留你的證件正本。要求抵押正本的業者，目的可能是防止你向其他家借錢，或是後續用以進行其他非法冒用，這完全是不合法的行為。當你為了急借一萬而交出證件時，很可能失去的遠比這一萬元更多。

    

5. 第五招：是否巧立名目，預先扣除各種「手續費」？

    

   這就是所謂的「九出十三歸」陷阱。比方說，你明明契約上寫借錢一萬元，但對方卻以「手續費」、「開辦費」、「保管費」等理由，在撥款時先扣掉兩千元，你實際只拿到八千元，但還款時卻必須依照一萬元的本金去計算利息和償還。這變相大幅提高了你的實際借款利率，也是一種不合法的收費方式。合法的費用會明確告知，並計入APR計算，不會用這種偷偷剝削本金的方式進行。

    

資金再急，安全第一：走對正規管道才是真解方

面對突如其來的資金需求，尤其是像急借一萬這樣看似金額不大、卻足以影響生活步調的狀況，焦慮的心情我們都能理解。但正因為急，才更需要冷靜。踏入一個錯誤的借貸陷阱，後續的滾雪球利息、暴力討債等惡夢，會將你從一個短期的財務缺口，推入長期的債務深淵。與其冒險接觸來路不明的廣告，不如多花一點時間尋求正規管道。例如，許多銀行提供小額信貸或信用卡預借現金（雖利率較高，但仍在法定範圍內），也有政府輔導的信用合作社或勞工貸款可諮詢。此外，向親友週轉，並立下清楚借據，有時也是更有人情味且安全的選擇。記住，任何正當的借錢管道，都不會利用你的「急迫」作為剝削的武器。保護好自己的個人資料、信用狀況與人身安全，是比快速拿到錢更重要的事。下次再看到「急借一萬」的閃亮廣告時，希望你能會心一笑，運用今天學到的知識，為自己的財務安全做出最聰明的判斷。
