There are some real similarities to what I have which is Mast Cell Activation Syndrome……your body reacts to foods w any histamine in them to speak of. I was sick and tired of being sick and tired literally and the regular protocol for this is vegetarian eating that made me so much sicker . I decided that I would eat according to my blood type from the book Eat Right 4 Your Type. So I went on the Carnivore diet by Shawn Baker. I am O+. Which was formed by meat eaters. Holy moly, I started to get well within 12 hours after about 7 months virtually in bed w horrible brain fog. My problems started as a reaction to the covid booster. Boom! Lesions all over….food made me worse histamines went crazy. As soon as I got on carnivore, it all stopped. I eat no histamines to speak of. Mayo didn’t know what to do w me either. The only Dr. Who honored what I told him 5 months after I got myself well, I thought, was an allergist immunologist . He did blood work that screamed histamine imbalance and put me on GL infusions once a month. But he told me “ you saved your own life! “……… I do have Ehlers Danlos and apparently 30 % of us can acquire this problem. However I’ve been approached by at least 6 others who could not get well and who don’t have EDS. They also had huge success on Carnivore diet. Shawn Baker is on You tube too….I got his book….you might want to check it out. What have you got to lose?
