Redness, swelling and pain in the buttocks indicate that the infection is caused by inflammation, pain relief can be oral pain medication, such as fenbendazole or celecoxib, tramadol and other symptomatic treatment, and you need to identify the site of infection and the cause of the infection. If there is a folliculitis or soft tissue infection under the skin, this suggests a possible Staphylococcus aureus infection. If oral antibiotics, including cefixime or cefradine, are needed, and the treatment plan will be determined by the infection. Oral antibiotics may be given if there are hard, red, swollen subcutaneous nodules. If there is a local fluctuating sensation and the texture is relatively soft, it means that the abscess is formed internally, and the abscess needs to be incised under local anesthesia, and then the wound continues to be changed. If there is redness, swelling and pain around the anus, it is caused by perianal abscess, and the infecting bacteria are mostly E. coli. For the treatment of perianal abscess, surgery is recommended, including abscess incision and drainage or radical surgery of the abscess.
