Hi. Numbness to the chin and lower lip, as in your case, is attributable to many causes including bone infection, bone tumor/ cancer, trauma. Since you have a history of being operated for Ca Tonsil, it would be advisable, in my opinion, to get an OPG X-ray done for your jaw as a primary screening. Screen yourself for diabetes as well. Diabetes also causes peripheral neuropathy in certain patients causing lack of sensation in certain nerves. I would advise you, as I do in case of all my patients, to not ignore this symptom and get yourself properly examined. Regards.
