I recently noticed that there is some redness (pretty much a straight red line) very near my vaginal opening (located at the bottom of my left labia minora). There is no pain, no discomfort whatsoever, no itching, no swelling, no burning on contact with water, no abnormal discharge. For all I know it could have always been there since it is in an area that is usually hard to see even with a mirror.
A week ago I went to an adventure park and did quite a bit of climbing. I was harnessed with a special safety rope but when I went down a long zip line, all of my body weight was concentrated in my pelvic area and it really hurt my vagina. Could this be some sort of very minor straddle injury? I do remember the red line hurting a tiny bit a day later, which is why I had a look in the first place. The discomfort went away very quickly but the red line/redness remains.I know that area has a lot of blood vessels and can take a while to heal, but I am still a bit worries (I have always been paranoid about STDs etc).
Since it doesn't cause any discomfort (it just bugs me because I know it is there), should I just let it heal or do you think I should go to the doctor?
Many thanks!
