I have a healing absence that was drained and i feel another one growing under my old absence which is located under my arm?

Abscess?: An abscess is a tender mass almost always caused by infection. Inside they are full of pus, bacteria and debris. The armpit/axilla is one of the most common places. Unlike other infections, antibiotics alone will not usually cure an abscess...incision and drainage is needed (such as you received). When they recur, there may be a cyst or pouch that has to be cut out. Your Doctor can advise.
