mild tingling lips and chin only when touched

since last one month... i have weird feeling at the area of lips and chin... like some mild tingling only when i touch or rub my lips or when i lick my lips by tongue... sometimes i feel the sensation on gums... i went to dentist.. he said me its a nerve issue... he gave me neurobion forte tablet for 2 months... if anyone experiencing the same... please reply??

My wife started like that and despite about four years of Maxillo Facial appointments it progressed to numbness from under her nose to chin with difficulty in chewing. She has had various drugs and even accupuncture that has not helped.

I get numbness well a strange feeling in my left side of my lips had this 7 years and no answers all I do is panic maybe this could be a reason for me to explore more
