Hi, I am 15 years old and I have been using tampons for about a year. I have always had strange aches down there but within the last few months they have been getting sharper. On a pain scale of 1 to 10, I rate it an 8 or 9. They only last for a few seconds and happen 3 or 4 times a day. The strange part is that it occurs in my vaginal area and not in my ovaries or hips. It can't be TSS because I change my tampon every few hours.
