About 3 days ago, my boyfriend and I tried avoiding having sex because I was on my period. Instead we grinded and I got these painful blisters
close to the inside of my vagina
due to the friction from my pad. Now, it hurts whenever I walk or sit at a certain angle. How can I ease the pain? I want to avoid going to the doctor but is it serious enough that I must? If I don't see a doctor, how long will it take to heal?
