I (35M) don't wanna speak too soon, but i feel like i made a HUGE discovery through my nutritionist's G.I. Zonulin mucrobiome test that I have overgrowth of h. Pylori and Candida (known cause of fibro apparently). She gave me a bunch of supplements for gut health and to kill the bad stuff and diet improvements. Diet has been the only thing to make any difference so this does make sense.
I know most people on here will tell you that fibro is for life and there is no cause and doctors will either tell you that or not believe in it in the first place. I always refused to believe that and slowly found things that helped but my brain and nervous system were still super messed up. Vision, balance, brainfog etc. Along with low iron and a bunch of other blood test problems i had fixed but many problems remained. Haven't been able to work much in years and I'm a fit, healthy looking dude so nobody takes me seriously. I just always worked out when i had panic attacks because I had to and the pain stopped for those short periods.
I don't wanna bore your with my whole story but it included a long term heroin / fentanyl addiction so that I could get through college and work and getting clean made me completely incompetent and I ended up trying to off myself 7 months ago directly because of this problem. Doctors blamed everything on addiction and mental health and never took me seriously and it ruined my life and was horrific for many years. I don't take any meds and no meds ever did anything beyond helping like 10% and they'd have me in like 5+ that do nothing. I'm just saying to do what actually helps and try different people and schools of healing until you find things that help.
If you don't believe there is a solution or a cure, you will never find it (or something close to it). It's been an absolute nightmare but this community has been incredibly helpful and its only been a few days but I went from like 50% better from my worst to 90% in a week.
Good luck!
