i have a sensitive area on my left thigh, very high up almost next to my vagina. it looks almost like a round dot about the size of my pinky tip (smaller than a dime) , with two dark lines above it. it is usually painless, unless touched or rubbed against clothing. my boyfriend noticed it and freaked me out about it. as i am in classes and working and barely have any free time for myself, i havent had time to go to a doctor (what kind should i even be seeking out for this type of issue?) and would like to know if this is an urgent matter i should seek medical assistance for, or if i could take care of this on my own. thank you in advance!
