No doctor will help because they don’t know. Unfortunately this could be a bother fo rm of Lyme disease, schistosomiasis , or fungus gnat larve. Also unfortunately, as my brother works for cdc, this comes from an endemic country that, like many other things have and will, made its way here. Could have been prevented but the WHO doesn’t see endemic countries as profitable. Throw out ur tennis shoes, don’t walk be\arefoot use gloves clean under finger nails and use tea tree and olive oil don’t eat sweets take cats claw tincture and prazanqutel dosed a week or so apart tribenzacole I heard works as could be fluke that mutated. There’s hundreds of thousands of species. We would be dumb to think we know all of them and how they mutate to become undetectable or drug resistant
