TMJ? I clinch my teeth and have numbness in my face, goes to my nose,my jaw is sore and teeth hurt

Some of your symptoms are similar to those that occur with TMJ although numbness does not appear to commonly occur in the disorder. TMJ takes many forms and many different symptoms are associated with it. In fact TMJ has been called the 'the great imposter' - this can make diagnosis difficult.

What you really need to do is have your physician/dentist examine your bite and do tests (x-rays, etc.) to find out whats going on. TMJ can be caused by muscle or joint problems and many different treatment options are available but first you need to find out what is causing the numbness and pain.

You might want to try the Health Central Symptom Checker and see what it has to say.
