this happens every now and then . i get really swollen armpits underneath . a lump under each one which hurts  to touch and sometimes causes pain under my arms in movement . now i have got a lump just in my right armpit which is the same . what is this ? as it keeps returning sometimes in both and sometimes one
Thank you for using Chat Doctor. The lump that develops under your armpit is an enlarged lymph node. The lymph node gets enlarged due to various reasons, the most common being, an inflammatory/infective condition. The armpit is also the area where sweat gets collected and there could be obstruction of the sweat glands. Proper hygiene in those areas and a course of antibiotic tablets/ointment should resolve the problem. Do consult your local doctor for the necessary medication.
