For at leas the past 3 months, about 7-10 days before my period, I get a bump on my mouth. It's only one bump, and it seems to be tracing across my mouth. The first time I noticed it, it was on the left side, now it's almost in the middle. I only get these before my period. At the same time, I also get redness and sores where my legs and outer genital areas meet. The dr. has given me medicine for it, and it seems to help. This rash can be very painful and the sores sometimes open up and bleed. It only happens during my period. I also get a yeast infection before my period. Wonder if the yeast infection and the bump and rashes are related? Anyone heard of this or experience it? What should I do next?
