I am so sorry you are having to go through this medical nightmare! Many of us here,...most in fact,...have gone through the very same thing. We try not to frighten one another. Having said that,...I think you have a fungal infection that needs immediate attention. I hope the two short youtube videos I am going to link, don't scare you.
I wish that your Doctors would watch it too,...but I'm dreaming. Candida Albicans would be my guess.
