Hi, i too have cervical spondylosis, you have my sympathy, its no fun!! I am waiting for spinal injections to see if they help. I felt exactly like you 8 weeks ago after stupidly stripping wallpaper. I am alot better now, I can walk for a good couple of hours before the pain sets in. I know what you mean when you say your head feels so heavy, The first couple of weeks I lay down almost constantly. The problems with your muscles may be spasm, I think mine was. I made sure to take the anti inflams and pain meds regularly (just stop start is no good) this builds up a 'therapeutic level'. I also used a combination of hot and cold packs - this is a tricky one, hot is good for muscle relaxation, but ice is good for the arthritis. Watch your posture, its amazing how easy it is to over stretch the neck. It does get better, just take it easy and dont stress, that can make the spasm work. Almost forgot, I also had a copurse of acupuncture for 6 weeks and I swear it helps every time it flares (and it will if I keep insisting on doing the wrong thing). Anway, good luck and let me know how you get on, CaroleX
