Tongue bumps may be caused by trauma, canker sores, enlarged papillae and certain medical conditions, such as diabetes and anemia. Are there other symptoms present? If one or more of your taste buds becomes inflamed or irritated, it can swell and also form a painful bump on the tongue. Usually, these resolve on their own. However, if this persists, I would recommend that you have this evaluated further by your doctor for proper management.
