So when I first got sick I became intolerant to sugar and carbs pretty quickly. I would get increased heart rate and it would also pound sometimes. Fast forward a year later I've become intolerant to almost every food or supplement/med I ingest. Basically my whole body feels like it becomes inflamed. My heart will start pounding to where it beats against my ribcage, this then can spread throughout my entire cardiovascular system. It pounds in my hands, neck, artery in my back, the arteries in my arms, the arteries in my knees, lips, nose, temple veins etc. And these reactions would typically go away but now I'm having pounding 24/7 that doesn't go away with rest anymore. If I continue eating the food I'm reaction to I can get weird nuero issues like confusion, disorientation, and panic. I've tried antihistamines and they don't seem to help. In fact they can actually bring on the pounding. I'm at a total loss at what's causing this. Please if their is anyone out there experiencing similar symptoms please let me know! Sorry for my rant.
