Pitted keratolysis

h

So I've self diagnosed my feet with this. I googled everything about what the heck is on the bottom of my feet. Has anyone had anything like this? It comes and goes. I put lotriman on it every night and soak my feet in tea tree oil after I shower. Wondering if I'd be better off just going to the dr and getting a prescription for it. Wondering if it's worth it though. Anyone?.
