I was wondering if this was a candida problem and were you treated with fluconazole? You only said heavy duty meds which left me wondering if the yeast problem was treated with an anti-fungal medication. How long did it take for the intense pain to go away? in my experience I have found most doctors don’t seem to consider the possibility of yeast being the culprit. I have been doing well with Metformin for 7 years, but my doctor thought I had suddenly developed an intolerance for it.
