<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have been getting small lumps that sometimes have puss in them, on my armpit. They are very painful and keep reoccurring. I have taken anti-biotics and that only solves the problem for a small amount of time as they eventually come back. They seem to be getting more painful and frequent. What shall i do  <response>: Hi! Thanks for writing to us! Well, formation of pus indicates kind of recent infection and necrosis of tissue; therefore, if were your family physician and had you consulted me for the recurrent pus formation in the armpit area, I would just think of a few possibilities like:1. A ruptured and infected epidermal cyst 2. Tuberculous infection3. Hi Chat Doctor. Inflamed fibrotic disease in ectopic mammary tissue as in females!Therefore, you need some microbiologicalhistopathological testing for confirmation and thereafter the line of treatment could easily be decided by your surgeon! Please revert to us if necessary. Wishing you early recovery!
