I get recurring lumps in my armpit. The lumps are sized bigger than a grape or marble and is hard and painful! The lumps occur on both sides. The lumps stays on for 2 weeks and then subsides a bit. Within few days, it flares up again. At this point it is difficult to move my arms cause of the pain. Sometimes the pain radiates to my arms and shoulders. One lump in right side formed pus and is leaking pus for over 2 months without a break. Have taken 1 course of Augmentin 625 mg (twice a day for 5 days last week) but lumps are still persists! Have taken other antibiotics over the years for this problem but no response. None of the other lumps have formed pus.
