Any over the counter antifungal will do the trick. You can use the spray like Mykaylas or a cream. Please do not use bleach/alcohol/peroxide etc. They put at risk for worse infections by decreasing your own skins healing and infection fighting mechanisms.
And by your bf some anti foot fungal products and extrs socks so you can avoid further contamination mauve need to wash your bedding & bleach shower n such n start off fresh
I agree with bunnykissy that mixture works very well I used it on my daughter but also doctor should give u oral antibiotics. So if they're refusing to do so you may want to buy some triple antibiotic cream or anti fungal cream.
Tea tree oil and mix it with coconut oil at whole foods.
Get some blue star ointment. It will clear it up quick!
I got ringworm just under my breasts on the side, where the bra strap covers... I used lotrimin extra strength spray for about a week or 2 until it went away
