well i can honestly say I feel your pain. I am 2.5 years pos treatment (yeah) and generally doing wel. I have had alot of pain the lasat 6 months, both from scar tissue and neuropathy.
Like Eric, i do take neurontin, works amazingly well for neuropthy. Neck pain is different. I need to streach my neck several times a day and still take some pain meds every few days when it realy gets out of whack, mostly I take Tylenol 4.
I also use one of those stick rollers that athletes use on sore mucsels. Works pretty good

It does stink, but it is something I can quite easily mannage

Good luck,
Steve
