I'm currently experiencing flaking of skin on the right side of my groin. it's not itchy, a little redness in a part.

Fungus vs seb derm: this sounds like a t. cruris, which is fungus in the groin. could try some otc topical antifungal cream twice per day for 2 weeks...if no better, see a dermatologist

Confirm diagnosis: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
