What causes severe pain in the pelvic area after drainage of a lump?
Patient: HI I have a large lump that has tripled in size since being put on antibiotics. We drained it this morning and there was yellowish-green pus followed by blood and a bad odor. The size has not gone down. Now my pelvic area hurts and there is a large internal  lump on my let side. I was told it was a staph infection. What is this really? Doctor: Hello and Welcome to ‘Ask A Doctor’ service.I have reviewed your query and here is my advice.As per my surgical experience, the lump in the pelvis suggests an infected boil or sebaceous cyst. After clinical confirmation, it requires definite intervention. Hope I have answered your query. Let me know if I can assist you further.Regards,      Dr. Bhagyesh V. Patel
