What do you think could be causing my pain?

3 years ago I had a really bad yeast infections. The doctor looked at my vulva skin and said I had a yeas infection. I got 1 yeast medication for that. I still had symptoms on my skin. Itching, burning, crawling sensation, redness etc. so I went back to the doctors and they prescribed 1 week of yeast antibiotics, with a yeast cream. Still didn’t feel right after all that. My skin was just inflamed and sore as hell. They took a vaginal swab and everything was clear. I still was feeling like something wasent right. So they kept prescribing me yeast medication for almost a year. The gave me over 1000 vaginal creams for every skin infection and yeast infection. Nothing worked. And I ended up with a severely dry vagina. I was still feeling really painful and sore. Fast forward to now. I have aerobic vaginitis, bacterial vaginios, low lactobacillus. And I think I still have dryness but not as bad. Currently working on getting rid of the bacteria’s and getting my lactobacillus up soon. Also have a urinary tract infection. My labia majora area is chronically burning 24/7, feels raw, looks slightly red, electric shocks sometimes, crawling sensation, and just very painful to touch. I was diagnosed with tight pelvic floor and vaginismus. I have this weird thing that I can’t really eat anything without it causing burning on my labia majora. Tmi but bowel movements make my labia majora pain worse. Currently on amitriptyline 20mg. Working a little. But not much. They worked at the start I think. But they are not giving me much relief. Also painful to walk because of my vulva being in constant pain. What the fuck could this be?
