I wore a pair of pretty tight denim shorts yesterday, and halfway through the day, I noticed the seam of my shorts digging into my crotch, and I had an on-and-off burning sensation in my vagina. Today I wore a skirt so not to irritate that area, but all day, on and off again, I felt mild slight pain in that area. What could have happened? Is it serious? Could I have torn my hymen? (I'm fifteen years old, by the way.)
