I have frequent numbness in left side tongue, jaw, head, neck and arm, for about a week now. pain in left eye, head and neck.slight pain in left chest?

Many possibilities: These problems can only be uncovered by a complete evaluation by a dentist experienced in the diagnosis and treatment of tmd's. Another more serious possiblity is referred symptoms from a cardiovascular problem. I urge you to seek help asap to rule this more serious problem out first.

See physician: There may be a tumor or a heart condition that needs immediate attention... See a physician asap to get an evaluation to rule out a serious condition and get appropriate treatment..
