Rheumatoid arthritis patients resulting in arm pain symptoms can be treated with medications such as non-steroidal anti-inflammatory drugs, glucocorticoids and antibacterial drugs. Rheumatoid arthritis is a joint inflammatory reaction disease caused by group A beta-hemolytic streptococcus infection, which mainly leads to joint pain and symptoms, and can involve the knees, ankles, elbows and other large joints, a single joint or several joints at the same time, and the symptoms of joint pain can be subsided within 2 weeks, and the treatment is mainly based on drug therapy. Non-steroidal anti-inflammatory drugs such as Loxoprofen and Indomethacin can effectively eliminate joint inflammation, relieve joint symptoms and help the recovery of erythrocyte sedimentation rate; glucocorticosteroids such as hydrocortisone and dexamethasone can play an anti-inflammatory role; and antibacterial drugs such as Benzathine penicillin and cephalosporins are mainly used against hemolytic streptococcus bacteria to remove the infection foci.
