I have recurring bumps under my arms, and around my genitals. these bumps range in size from a pimple to quarter size. sometimes they are sore and sometimes not. I went to my gp and he diagnosed me with pyoderma, and prescribed sulfameth or Bactrim. the bumps go away for a month or so then come back. recently I developed one under my left arm that is very sore, and oozing white pus, and a little blood, I have been washing my armpits and genitals with hibiclens every other day since I was diagnosed, but the bumps always come back. is there an underlying problem causing this, and if not, what can I do to control these bumps without antibiotics and expensive hibiclens ? thank you!
