Introduction
Pain in the kidney area of the lower back is usually caused by factors such as lumbar muscle strain, kidney stones, renal cysts, nephritis, and fasciitis. Targeted treatment should be based on specific conditions. If symptoms worsen or persist, prompt medical attention is necessary. Patients should avoid maintaining the same posture for prolonged periods, sit upright with a straight back, and avoid slouching or bending over to prevent aggravating the pain.

Pain in the kidney area of the waist is usually caused by factors such as lumbar muscle strain, kidney stones, renal cysts, nephritis, and fasciitis. Targeted treatment should be provided based on specific conditions. If symptoms worsen or persist, timely medical attention is necessary. Specific details are as follows:

1. Lumbar Muscle Strain

Remaining in the same posture for prolonged periods—such as sitting or standing for long durations—or engaging in intense twisting movements may stretch the muscles and fascia of the lower back, causing pain. Avoid overusing the affected area and allow the lower back adequate rest.

2. Kidney Stones

Insufficient fluid intake, metabolic abnormalities, and other factors may lead to increased levels of calcium and oxalate in the body, resulting in kidney stone formation. As stones move within the body, they can irritate the renal mucosa and cause pain. Extracorporeal shock wave lithotripsy can be performed to break the stones into smaller pieces for easier expulsion from the body.

3. Renal Cysts

This is a benign kidney condition that may cause flank pain. Renal cysts typically do not produce symptoms, but if a cyst ruptures or becomes infected, it may lead to pain and other symptoms. Under medical guidance, analgesic medications such as ibuprofen sustained-release tablets, celecoxib capsules, and pethidine hydrochloride tablets may be used for treatment.

4. Nephritis

Factors such as genetic predisposition and autoimmune dysfunction may lead to nephritis, which can stimulate surrounding mucosal tissues, causing swelling and pain. Antibiotic medications should be taken under medical supervision, such as cyclosporine soft capsules, azathioprine tablets, and prednisone acetate tablets.

5. Fasciitis

Fasciitis refers to pathological changes in the fascia that result in various discomforts in the musculofascial system, including pain, muscle tension, weakness, spasms, numbness of the skin, and movement disorders. It is recommended to follow medical advice and use medications such as eperisone hydrochloride tablets, celecoxib capsules, and meloxicam capsules to alleviate symptoms.

Patients should avoid maintaining the same posture for extended periods, such as prolonged sitting or standing. Sitting posture should be correct, with the back straight and avoiding slouching or bending forward, to prevent worsening of pain.
