Any Suggestion For Weird Skin Tag Located In Fold Of Leg That Causes Itching In Thighs And Butt ?

The back of my thighs up to and including my butt have been itching almost non stop for a couple weeks. There is no noticeable rash, raised bumps or anything. I have not changed soaps, detergent, or anything. The only other thing I noted was what looks to be a weird skin tag that showed up almost overnight that was red and sore. No head like a pimple and only bled when I tried to squeeze it to see if it was a pimple or small cyst. It is located in the fold of my leg to the right of my labia. I have tried lotion, antifungal cream, tea tree oil. Nothing helps or doesn't for very long. The itching is driving me crazy!!
