Nephritis does not cause hand and joint pain, unless it is caused by autoimmune diseases or rheumatic diseases, such as systemic lupus erythematosus nephritis, rheumatoid arthritis caused by nephritis. It is also possible that the patient’s nephritis has a very long course, resulting in disorders of calcium and phosphorus metabolism, resulting in calcium deficiency and thus causing joint pain, or the patient’s long-term gout is not well-controlled gouty nephropathy, resulting in hand and joint pain due to the large amount of uric acid deposition. You can also apply local heat to the painful area to improve blood circulation, promote the dissipation of inflammation and absorption of edema, and reduce pain symptoms, or take non-steroidal anti-inflammatory and analgesic drugs, such as celecoxib and ibuprofen, under the guidance of a doctor.
