Atm treatment

Hs anyone heard of numb chin syndrome ?And what tests are around to test it.My pain has always been in the mental nerve area-unless the pain is so bad I end up squinting and then the rest of the branches hurt on that side-but that goes away fairly quickly.So the pain is in the mental nerve area and into my chin.
I have been asking for tests on my chin itself but have not had a doctor interested in doing that.And I clicked on something and I for Numb Chin Syndrome ,which is quite serious and can be a predictor(for want of a better word) of cancer.
Just asking-does anyone know of this and if so how can I get tested.?I am at the point of just wanting to carve that part of my face away.
