I recently had tonsillitis and while I was spending a whole week in bed, an itchy red patch appeared on my inner thigh, towards my groin. I've been better for a week and just been ignoring it but it's been itchy and yeah, it's dry and flaky as well. I'm a 16 year old male. And it's not herpes, seeing as I haven't done anything sexual to get it.. It just appeared. I'm thinking it's eczema or jock itch or something. What should I do to get rid of it?
