Hello, I have been dealing with all of the same..I have no answers, very frustrating! Moderna booster 12/15/21, GI symptoms began soon after..esophageal tightness/slow gastric emptying/horrible bloating & uncontrollable flatulence. Sorry, so awful! In January the hives began and have remained. Dermatographia.. started very itchy back/arms/legs/hands/feet..
face & ears would get red and hot, usually in evenings. My labs showed nothing. I’ve messed around with my diet and fasting, the only thing that helped was water fasting but the hives returned as soon as I began eating again, even with a histamine elimination diet. Researched and listened to some Dr Berg info..started taking some of his supplements and others..nothing has made it go away. I usually take a Claritin in AM & Benadryl at bedtime..typically keeps the hives at bay. I don’t feel particularly stressed or anxious. I have always been very healthy with zero allergies. I’m baffled. Any help or answers would be amazing!
