need some help. i have i spot between my pinkie and toe next door that is killing me. where the two rub together is a patch of skin and it burns. any thoughts?

i run/walk everyday. it's getting so painful to even do that. i don't want to see a doc. anyone ever had this. it feels like it goes up my toe. whaaaa!

It sounds like athlete's foot to me, or you may have a soft corn starting.

what can i do for that? what causes corns?
