Hi
Welcome to the MedHelp forum!
It is difficult to diagnose without examining the lesion. If this area on the underside of tongue has become inflamed then it can be a canker sore, inflammation of the tongue itself, allergic reaction, oral herpes simplex virus infection, tuberculosis of the tongue, localized bacterial or fungal infections, or early-stage syphilis. Chances of cancer are less but should not be overlooked.
Please consult your PCP for primary examination followed by proper referral.
Hope this helps. Take care!
