The cause of red bumps in the joint area is mainly formed by local folliculitis and sebaceous cysts (powdery tumors), which are caused by poor pore or sweat gland secretion, resulting in the accumulation of dirtier things, which can lead to local infection and redness. Treatment is mainly conservative and surgical. Usually patients with milder or earlier onset can be treated with anti-infection therapy, such as penicillin, cephalosporins, quinolones, macrolides can play a very good anti-infection effect. During the treatment period, it is important to eat a light diet and not to eat spicy and stimulating foods. If after the above treatment the effect is not obvious or the condition is aggravated and there is suppuration, surgical treatment should be taken to complete excision or drainage of the pus inside, local sterile dressing dressing, regular wound dressing change, with the application of anti-infective drugs for comprehensive treatment.
