What Are Causes The Painful Bumps Under My Tongue?

Has there been any injury?
Accidental biting of the tongue during eating and chewing, and injuries to the tongue from the teeth sustained during an epileptic fit will obviously give rise to pain. Luckily, the tongue has a tremendous ability to heal itself without infection taking place and usually this is the case.

Can you see or feel any ulcers inside the mouth?
Shallow but tender ulcers on the tongue, gumes or inside cheek are often associated with minor viral illness.

Are you a heavy smoker?
There is no doubt that heavy smokers can develop inflammation of the tongue as a result of altered bacterial coating on the tongue together with nicotine staining and build-up of 'fur'. Cutting down or stopping smoking is important and usually does the trick. Antiseptic mouthwashes may speed up recovery.
