I am 21 years old.I have a terrible itch when it comes to my private area. Its so bad that I can't even sleep sometimes because it keeps itching. The area that itches always look kinda pale and swollen. It also look dry like a rash. The discharge is thick but white and it sometimes turn to grey and yellow. It has a strong odour. I also have a small lump under the skin above my clitoris on the left side, it doesn't hurt until I apply pressure. I became sexually active last year but I always protect myself. What could it be I'm very worried and would like your help. Thank you.
