Hi Peter,
I too had a similar issue with my neck. I have PSC and have been recovering for about 16 months and had a SLIP at work and whiplashed my neck.... again and am now in full blown symptom mode again....

I have started seeing a chiropractor who specialized in neuro/chiropractic and it is helping. I am also doing intense massage therapy with it as well as limitimg all of my exacerbation factors. Its super slow but I am making improvements.

When my neck is aligned properly it really affects how my brain functions.
I also use heat and I take frequent breaks. I have a properly fitted chair with a high back at work that helps as well.
