in my period it burns when i use the bathroom the pain is severe and i normally can't do anything till it goes away. i am only 19 years old have never had sex and this problem has been going on for about three years the doctors don't know what it is. when i am in my period it burns to go to the bathroom and it's sharp shooting pain. the pain lasts for about three to four hours and i can't do anything normally during this time.
