Hope that all goes well with the nerve block, and that the tmj stuff can be improved. I think so many of us have multiple issues which complicates what's ES, and what's down to the other things... Your other cervical issues will undoubtedly affect it too, I have a slipped disc C5-C6, and that has improved, but doesn't take much to start playing up again, and have lots of knots which never seem to go completely...
