Sex: Female
Age: 17
Problem:
I came home from work today and took a shower as usual. When i got out my inner and outter labia were extremely itchy, i used some vagisil and went to take a nap. In my sleep i must have scratched myself or something because i woke up and my right inner labia was extremely swollon along with my clitoral hood. I filled the tub with cool water to try and take down the swelling, but it didnt help much, and i realize from the stinging that i had a few papercut sized cuts as well.

Do you think the inflamation is from the irritation of the dry skin and itching/small cuts or do you think it's a yeast infection?
I also have my period and have been using tampons/pads so my skin could have just been extremely dry?
Also it's not any sort of an STD, im abstinent.
Thanks for the help!
