I've had an itchy rash at the very top of my inner thigh for a couple of weeks. It's just where the leg meets groin, sort of on the knicker line. The rash is almost semi-circular and the skin is raised. It doesn't itch all the time, maybe just a couple of times a day, and it's worse at night (which is why I'm up now). I've been putting E45 on it twice a day just to see if that helped and if it was just dry skin of some kind, but it's not making any difference. Any ideas what it might be and if I need to go to a doctor - I can't really get there until next week as it's not an emergency, but when it itches, boy does it itch!
