Can anybody advise on this. I have had a sore tongue for 10 months. I have seen my GP who has no idea why. He carried out the regular tests; full blood count etc. nothing showed up. My dentist suggests that it may be an allergy to sodium laurel sulfate found in toothpaste (SLS) and other body products. It's driving me crazy as my tongue feels like it is burning. Just wonder if anybody has suffered from this and if they found out what caused it or have advise on how to cure it. petite items to wear for maid of the brides
