My son was one of the ones that did have a lot of pain under his tongue for quite some time when he finally went to his dentist who referred him to an oral surgeon for a biopsy and finally to an ENT at a Comprehensive Cancer Center. If you check out the the "forum home" link at the top of this page and go to the first item "New Posters read this" link you will have a good idea of what questions to have for your doctor and for anything you might want to ask us about here. I'm so glad you found us. Lots of helpful people here.
