It has been so long since I’ve posted here. I have found something that actually helps and it’s not a RX. When you apply this you have to be prepared that it will burn and will burn more than your mouth does now and use it daily and then start decreasing it until you use it once a week. I use Capsaicin. The burn goes away in about 5 to 7 minutes. It will not blister. I put it on the finger then run water over the finger to remove any of the capsaicin I can see. Then where ever your mouth or tongue is burning run your finger over it. I’m now in my eighth week of using it and it has helped my bms by 98%. Just start with a weak solution and build up. You will be amazed. Capsaicin works by disturbing the pain signals from the nerve to the brain. I wish I knew about this 25 yrs ago. It’ll cost you a few dollars and you don’t need to back it up with any other meds. I hope you get the same result I have.
