Hi..I have received my bottle of Neuroveen, not because I have been diagnosed with nurropethy, but because I have every system of that in my back. (the burning, itching, swelling, redness, jumping, etc.).I tried it for the 1st time yesterday, and immediately had the worst case of gas, heartburn, and burping.....is this even normal? The symtoms go down into my legs and feet, and well as my back. Thank you,
