Arm pain caused by rheumatic polymyalgia can be treated with non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids. 1. Non-steroidal anti-inflammatory drugs: common non-steroidal anti-inflammatory drugs include celecoxib, meloxicam and ibuprofen, etc. These non-steroidal anti-inflammatory drugs can inhibit the enzyme cyclo-oxygenase in the body to reduce the synthesis of prostaglandins to play an anti-inflammatory and analgesic effect, and it is good for the relief of the symptoms of rheumatic polymyalgia patients such as muscle pain, morning stiffness, etc. Glucocorticosteroids: glucocorticosteroids inhibit the synthesis of inflammatory factors and induce inflammatory cells. 2. Glucocorticosteroids: Glucocorticosteroids play a powerful and non-specific anti-inflammatory role by inhibiting the synthesis of inflammatory factors and inducing apoptosis of inflammatory cells, etc. The application of glucocorticosteroids, such as prednisone and methylprednisolone, in small doses, can achieve good efficacy in rheumatic polymyalgia and gradually normalize the laboratory indexes of patients. If rheumatic polymyalgia causes arm pain, it is recommended that the patient go to the rheumatology and immunology department of a regular hospital and take medication as prescribed by the doctor.
