<s>[INST] lump on armpit that is really after days of getting loads of pus out its really painful my girlfriend tried getting out what we perceived 2 be a ingrown hair due 2 the fact of black dots tried with a tweezers but its still sore she reckons there is something under the skin it really smells when the pus is squeezed out any ideas [/INST] Hi,Dear,thanks for your query to Health Care Magic.I studied your query indepth.In my opinion the recurring lump after loads of pus for many days,is a Chronic Furuncle- i.e.abscess in hair-follicle in  armpit, with surrounding cellulitis due to-chronic infection.Something underneath-is the feel due to  the indurated hair-follicle and the thick abscess wall of the chronic furuncle in the armpitis.Hope this answers your  query and solves your causative- query  for the armpit lump.Hope this would clarify the worry you had.Would love to Wellcome your queries to HCM. </s>
