Help with an infected boil
I am an older female, with a very large boil, where the top of the leg meets the rest of the body (where the underwear elastic would rub) on the inside of the groin area. The boil was about the size of a VERY large egg. It burst and now very foul smelling brown puss keeps oozing out. It is very very painful. What causes something like this? And I have been very sick, almost flu like symptoms. Very weak, very unsteady on my feet, terrible headaches and lots of body pain (aching). It's been hot here, but I have kept hydrated. Could this a staph infection or an infected lymph gland?
