Question: how to get rid of an infection on your arm?
Answer: Oral antibiotics are used to treat mild cellulitis; more severe cases must be treated with intravenous antibiotics in a hospital. Antibiotics that may be used include cephalosporins, dicloxacillin, clindamycin, or vancomycin. Swelling can be lessened by elevating the affected area, such as the legs or arms.
