Is the lump soft or hard? Most of the time soft lump is usually lipoma a benign fat tumor. Presence of pus in it usually indicates sebaceous cyst which got infected. I advise you to consult a general surgeon and go for simple excision of the lump along with a course of antibiotics. Hope I have answered your query. Let me know if I can assist you further.
