Perhaps invest in a good massage chair... Ive sat in some that do a great job on the neck area - it would save you money in the long run... Heat might help as well makes muscles relax - increases blood flow.
Hbo? I've never had it but that also promotes blood flow and healing - many here say it's amazing.
I'm okay - slowly crawling out of my radiation hole.

hope to be you some day! Take care and feel well.
