What causes a dull ache in the right side of the waist?

　　Dull pain in the right waist may be caused by poor posture, overexertion, lumbar muscle strain, lumbar disc herniation, kidney stones, etc., and requires management according to different situations. It is recommended to seek timely medical attention, identify the cause through examination, and then follow medical advice for treatment.

　　1. Poor posture: Long-term bending and sitting, such as office workers spending prolonged hours working at a desk, can keep the muscles on the right side of the waist continuously tense, leading to dull pain, often accompanied by a feeling of stiffness in the waist. Improvement can be achieved by correcting sitting posture, getting up and moving around at regular intervals, and performing waist stretching exercises, such as forward bending and backward extension of the waist while standing.

　　2. Overexertion: Frequently engaging in heavy physical labor, such as lifting heavy objects, or prolonged exercise can lead to strain of the right lumbar muscles, causing dull pain, which may ease slightly after rest. Daily routines should include reasonable arrangements for workload intensity, avoiding excessive fatigue, exercising moderately, and applying heat to the waist after labor.

　　3. Lumbar muscle strain: Long-term repeated pulling or injury to the lumbar muscles can lead to aseptic inflammation, resulting in dull pain on the right side of the waist, which worsens with exertion and improves with rest. Patients can use medications such as diclofenac diethylamine gel, blood circulation-promoting and pain-relieving plasters, and Yaobitong capsules under a doctor's guidance to alleviate symptoms.

　　4. Lumbar disc herniation: Degeneration or injury of the lumbar intervertebral discs can cause the nucleus pulposus to protrude, compressing the right nerve root, resulting in dull pain on the right side of the waist, which may be accompanied by radiating pain and numbness in the lower limbs. Patients may use medications such as ibuprofen sustained-release capsules, mecobalamin tablets, and Yaotongning capsules according to medical advice to alleviate symptoms.

　　5. Kidney stones: Due to increased concentration or decreased solubility of crystalline substances in urine, crystals precipitate and accumulate in the kidneys to form stones, irritating the renal mucosa, causing dull pain on the right side of the waist. The pain may intensify in paroxysms and is sometimes accompanied by hematuria. It is recommended to use medications such as Shenshitong granules, lithiasis granules, and tamsulosin hydrochloride sustained-release capsules according to medical advice to relieve discomfort.

　　Adjust posture and avoid maintaining the same posture for prolonged periods. Pay attention to local care in daily life, try to avoid strenuous exercise, and appropriately massage or apply heat to the waist to promote recovery.
