Out of options, reaching out

two years ago I had a serious accident which resulted in a 5 month long hospital stay and 2+ years of rehabilitation. For two years I have had recurring skin rashes, hives, dandruff (on eyebrows as well), toenail discolouration, weird penile cuts on foreskin, the list goes on and on. Main problem is, I live in a foreign country with no health insurance and have absolutely no money to go to the doctor. I managed to go to a doctor in the past and showed my rash and told the symptoms I've been having and when I suggested yeast (home research) one said No it is bacterial and referred me to a dermatologist whom was way too expensive for me to see. I'm not sure what to do anymore, I've seen doctors about this off throughout the past 2 years, and have gotten a whole myriad of anti fungal creams, shampoos, and even changed my diet to the no wheat/no Sugar diet. You name a supplement or vitamin and I've tried it. Probiotics, tea tree oil, coconut oil, reishi mushroom extract. lately I take zinc, vitamin C, and apple cider vinegar. Nothing. Still today, I have the dark red itchy rash between my legs, eyebrow dandruff, and other symptoms... Is this an STD? A bacterial infection? A pesky yeast infection? Something worse?? Can anyone suggest to me what this might be or what I should do... The times I have been to the doctors when I explain the many symptoms and show them the rashes that keep mysteriously coming back for so long... they seem like its no big deal... IM GOING INSANE

Thank you,
