I am a 17 year old girl. Recently, I've started to become very itchy, mostly like right around my breasts, stomach, and around like my pelvis and vagina. My scalp has also been pretty itchy. I'm not sure what's causing this. There is no rashes, just a little red from itching. The itching will last for a maybe 10-20 minutes at a time and then I'm okay, but it is the most annoying thing! Usually it starts when I'm sitting down or laying down, not really when I'm standing. The only sex I have had was oral, and so I don't think it really has anything to do with that. I want to know if maybe there is something I shouldn't eat or drink to make this irritation stop, or if I need to just use or try something? Any advice would be much appreciated asap! Thanks!
