Coarse finger joints need to be treated according to the specific causes (such as trauma, chronic strain injury, rheumatoid arthritis and gout), including drug treatment and surgical treatment. 1. Trauma: The swelling and coarseness of the fingers caused by trauma need to be sterilized with iodophor in time, and erythromycin ointment should be used at the same time. If the swelling is more serious, it is necessary to make an incision in time to drain the pus, and then carry on the treatment of anti-infection. 2. Chronic strain injury: For the finger enlargement caused by long-term chronic strain injury, the swelling can be relieved by hot compresses, rest and medication (such as diclofenac sodium, celecoxib). 3. Rheumatoid arthritis: anti-rheumatic drugs such as methotrexate and leflunomide can be taken to treat the symptoms of pain, and drugs such as Loxoprofen sodium and ibuprofen can be taken. 4. Gout: commonly used indomethacin, etoricoxib and other non-steroidal anti-inflammatory drugs to relieve pain, in addition to glucocorticoids (such as prednisone), colchicine and other drugs. If the finger has an unexplained swelling, it is recommended to go to the hospital in time to identify the cause of the disease and then treat it.
