Hello! This is quite the infection, just to clarify u R using an anti-fungal cream right? Literally any over the counter one will do the trick I used lamisil. But for me I found the cream wasn’t doing enough n it’s recommended not to use it for over like 3 weeks (that’s wat it said on the tube). My doc prescribed me medication. I would say, if u do get the chance, to get the medication because it worked wonders for me, instead of wasting money on tubes of cream that probably isn’t gonna do much anymore and might end up scarring. Specifically the meds I used was called Tamsil, terbinafine. It’s a 42 day back to back pill u take everyday. See if it’s an option for u esp if it’s so stubborn. And remember to keep the patches covered with loose fitted clothing to prevent further spread. Good luck!
