<human>: I found a lump under my armpit, quite deep, began messing with it and although it was difficult to burst, I pressed and pushed it enough and it burst and thick, green and brown pus came oozing out. It was painful before doing this but more painful after. I waited and thought it would just disappear, but now it has become a bigger, dome shaped/flatter, lump underneath my armpit, not so sensitive to touch. Ive waited about 4 days for it to go away but it is still there.
<bot>: Hi. It is difficult to say whether this was an infected lymph node or infected sebaceous cyst. Well, the treatment remains the same. A course of an antibiotic and anti-inflammatory medicines for at least 5 to 7 days. You have to undergo a proper clinical examination to be done by a Doctor who can catch many of the problems on your proper history and physical examination and can then guide for further investigations and treatment.
