Lump? Causes fill textbooks. To guess without benefit of examination would be counter-productive. Your Physician may think it's an infection, thus the antibiotic. If antibiotic helps, source of infection has to be determined and eliminated. Consultation w a specialist Dermatologist may be in order.
