Hello. I have had a pimple-like rash that has occurred on my thighs for at least a year, long before I was sexually active. I was diagnosed with bv earlier in December, and believe I am getting it again (yellow discharge, some itching, odd smell). However, I have also had pain in my buttocks and occasionally down my leg. This occurred before my diagnosis last time as well. Can bv cause pain down the leg? Or should I be concerned about other STIs, such as herpes?
