Hi, I recently switched my birth control brand, and the next day after switching I began to feel
sore in my genital area after
biking and exercising, which i figured was just from dryness, since that is a side effect. There is now one small sore, not really a blister, but with white on the surface of it, but i have not had intercourse in 4 months. Could this be herpes? or just a side effect from a lot of exercise while being dry?
