I am suspected to have a mast cell activation syndrome (MCAS/MCAD), which I'm learning is increasingly common with Lyme. I have a lot of food sensitivities, but the symptoms aren't anaphylactic, they are usually MENTAL! Bloating, and acid reflux.
My doctor prescribed a bunch of anti-histamines and mast cell stabilizers, but I am going the natural route for now - low histamine diet (SIGHI list), quercetin, nettles, bromelain, and vitamin C. I've been able to get off the Pepcid, and rarely get reflux now. I feel better on the strict diet.
Here is one of many articles you can find on MCAS and Lyme:
Lyme, Babesia, Bartonella. Symptoms began 5/2016, didn't start treatment until 9/2016. Slow but steady recovery.
