Nerve or muscular??

I have been to the docs (variety of them),I had cat scans and nothing shows up, which is a good thing too. I have a muscle that spasms above my ear on my head, according to the dentist it is a muscle spasm from tmj. I wore one of them top teeth mouth guards but it only made me worse so i stopped using it. My right ear always feels clogged and it feels as if i have a pinched nerve on that side of my neck. I feel i need to push behind my ear and push up around my neck to get some relief. Is this tmj or is it nerve/muscular? A year ago i was doing some stretches and i felt really odd after, all these symptoms suddenly came on. I get pins and needles on the right side of my head at times, my neck has a click in it sometimes, not a cracking feeling. My doc said one day i will wake up and be fine cause she don't know what it is.. I have had two cat scans and an xray, they are fine, and i saw a chiro. neurologist, physio etc. Neurologist said pinch nerves don't hurt. Any ideas/relief ideas?
