I have had burning mouth syndrome for 15 years I take Gabapentin 6 a day-- I am trying to get off it. seems to make no difference to pain but does help with the thick mucus that comes with this condition. I see the pain clinic every 6 months. I have had bowel cancer twice 20 years apart Doctors do not think it is connected - did have chemo with both. I also don't think it is connected as it started 7 years after the the first chemo. anyone have this condition?
