Hello. Thank you for writing to us at healthcaremagic This painful bump is a furuncle, commonly known as a boil. A furuncle is a skin and soft tissue infection (SSTI s). I suggest you to continue with Oral antibiotics for a week. My choice of Oral antibiotics would be either from a penicillin group e.g flucloxacillin Or from a cephalosporin group e.g cephalexin. If the bump is oozing pus, clean the area after washing your hands with a sterile gauze piece dipped in an antiseptic e.g betadine solution. In addition to Oral antibiotic you may use an OTC topical antibacterial e.g 2% mupirocin ointment, twice daily. An OTC pain killer e.g ibuprofen 400 mg twice daily will provide symptomatic relief from pain. If the bump does nt respond as expected Or increases in size and becomes more painful Or if you develop systemic symptoms like fever, likely it would have progressed to an abscess stage, which needs to be drained.
