The dizzyness could be B12 deficiency. I used to have SIBO (small intestinalbacterial overgrowth) and it caused most of the symptoms you mentioned plus I had constipation once in awhile. Issues with the small intestine cause issues with nutrient absorption, especially B12 and iron. I had it for a while and starting having a bunch of neurological issues from the lack of B12 and eventually had problems even orgasming! I saw a naturopath and she treated my gut and put me on supplements to replenish what I was missing. As a wonderful side effect it cleared up most of pelvic pain, including my endo pain. Digestive enzymes really help.

I suffered from much dizziness. I began B12. It has helped!
