I get any crap like that and they say there is no treatment, or treatment that only kinda sorta works sometimes, I am using colloidal silver.
Not a doc, ain't giving med advice, just sayin what I will do. I don't trust the establishment and big pharma to offer nothin much beyond "treatments". Ain't no money in cures, but buckets of bucks in "treatments" "tests" "go to another specialist", etc..
I pulled one that had dug in off the back of my neck the other day, here's hoping I didn't get anything.
