Canker Sores
These are some of the more common raised and tender bumps on the tongue. They're characterized by the Mayo Clinic as small, shallow lesions that can result from factors including food allergies, tongue injuries, vitamin deficiencies and an underlying medical condition. When they develop, these sores usually resolve themselves in a week or two. However, you can treat the lesions with corticosteroids, nutritional supplements and heartburn medications. Topical pastes of debacterol, benzocaine, amlexanox and fluocinonide can also speed recovery.''
