I keep getting (I have one now) boils in my inner groin area. I have one now. The swelling is as large as my (large) hand. Very red, but no head , and very painful. I ve tried many things in the past to get them to a head and rupture, but nothing works quickly . A doctor at the clinic I go to prescribed Sulfamethoxazole-TMP DS tablet. I haven t taken it, I m scared of taking extra drugs, as I m already on drugs for my thyroid, congestive heart problem, and assorted other problems. What is the best thing to do to get these groin boils to pop or go away???? They re huge and hurt so badly, especially to walk.
