Recently I have been takingmore frequently, because my free gluten sensitivity has increased. From what I read, the less free gluten you consume over time you get more sensitive to it. Anyway, I have been taking and have been feeling pain around my kidney area and stomach pain. The reason I take the Taurine is because it stops my msg attacks within 2-3 minutes, as opposed to ibuprofen which takes about 10-15 minutes to fully stop the . Do you think my kidneys will be fine? I try my best to avoid free gluten, but it's so hard to find things that don't have it. I hate going to the doctor. The pain around my kidney goes away about 24-48 hours after using Taurine. I take 500mg-1gm at the most when I have an attack. I did not have this pain around my kidney the first few times I used Taurine. The pain is almost always in front of my left kidney area.
