recently my left inner thigh (up close to my vagina) has been burning. It's only slightly red, and slightly swollen. It feels a bit raw and hurts if my other thigh rubs against it. Does anyone know what's wrong or how I can stop it? it's kinda a line and it's only where my thighs constantly touch/rub together.  Coconut oil has helped soothe it as well as baby powder. I'm gonna try Cortizone next.
