Just got to read this thread... Feel for you scorpio, hope you feel better.
I had my share of back pain to the point it would go black in my eyes if I made a wrong move in bed. Doctors called it “herniated disk” problem due to something stupid I did (pulled something heavy once, or took up the stairs some furniture that did not fit into elevator). The biggest relief though came not from doctors (aside from drugs), but from reading a book about back pain, and what exercises to do for different cases. I slowly figured what was helping me and did that. It took few years to fully recover.
I also used to have arthritis flares that would make things worse, and other similar problems explained by doctors in different ways, that I would sum up as "not fully understood quirks of immune system". All this for now is in the past (knock on wood), and to big point I thank my daughter for it. Years ago she went vegetarian, insisted on eating organically grown food, and few years ago even convinced me cut off meats and all heavy foods from the diet. For few years now I practically do not eat meat, animal fat, butter, or cheese. Most of the products are either locally grown or organic. I eat fish though, but not farm-raised. (I still cheat with piece of good steak every once in a while, but very rarely, and I do not crave for it anymore).
Getting to my point, I have not had any back pain or arthritis flares for years now and my blood tests improved a lot. I play sports and was never overweight, but with this change to my diet without much effort I came down 10-12lb and now steady at ~166lb (I am 6’ ). In general I feel healthier.
My daughter is now vegan, studying nutritional science at Cornell.
