looks like your immune system was compromised due to prolonged use of Antibiotics that caused you to have some form of fungal infection. yeah i suspect it might be candida. you might want to try candida diet. no FAT, no MEAT, no oil, no sugary starchy foods, just green vegetables like lettuce, brocolli. i include rice, fish, fruits on my diet though to prevent starvation but just a little of each of it and i dont eat it all at once. my diet is inspired by the comments in this forum and just less than a week of this diet blisters on my feet improved SIGNIFICANTLY. i have dishydrosis btw, i have this after i took the strong Antibiotic ciprofloxacin for my cough. hope this helps..
