Hi, well as someone who not long ago had a bulging disc between my 5th and 6th vert I sympathise ! whenever I tilted my head back and to the left my left arm would go numb.
Immediate suggetion is requesting Voltarol 50 mg tablet for inflammation from the docs and see if that helps.....
try an inflatable traction neck brace, sounds silly but a little light tracxtion might help and inflated not so much doubles up as a pillow.
worked for me, it was that or get a 6" needle through the front of the neck whilst AWAKE (yes, the front ! they don't go in the back because of too hard muscles and you have to be conscious) !!
Good luck, sucks being ill
