Poor with no medical insurance

Hello Doctor,

I occasionally get large welts around my waistline and buttocks. I have one now that sprouted up on my right hip at the top of my groin. This usually only happens when the days are very hot or when I'm wearing pants that are too tight (I walked around in really tight pants 2 days before this happened) I am a little overweight and I always wear a belt so I'm thinking it probably has to do with the way the skin folds on itself, sometimes wearing raw or causing chaffing. Now, I'm 26 and I have slept with 12 different girls. For the most part I do use protection and I always discuss sexual history with partners. I have had cold sores since I was a child. So at this point I'm worried. What do I need to do that would be reasonably cheap? Also, what would you diagnose this as? I hope this isn't too vague.

Not the Dr's site, but no one can diagnosis you over the internet. You would have to see a Dr and get a proper diagnosis.
