Sorry I have no idea if the mms is causing the problem for you but I had the same problem w/ my iron levels were really low and i never taken mms at the time I was takin caprylic acid and Black-Walnut hull then all of a sudden i could not eat anything w/o my stomach burning O I was aslo only eating veggies I was on the candida diet it was only until I started eating fruit again that the stomach burning went away I also ended up in the ER for passing out and the doc told me my red blood count was low maybe its a combination of the things you are taking
