My 15 month old son has a staph infection in his groin area.  It started out looking like a boil, since he has been taking antibiotics the redness has gone away.  Now there is a hardened oval area under where the boil was.  It doesnt appear to be getting smaller.  Could this be something more serious?  How do I treat it?
Dear I can understand your concern. I would like to inform you that some induration that is hardened area may persistent at site of infection. It will slowly go away. There is no need of any medicine for that, and it should not be any matter of worry.Don't press over that repeatedly. It may cause reinfection to that site and swelling can increase as well. Hope this will help you. If you have any other concerns please feel free to message me. Thanks for contacting Chat Doctor.
