I can't believe your medical complications in Canada. That really stinks, especially since you are in pain!!!!!!!!! I wouldn't jump too fast to the implant. Try not wearing hats, turtle necks, don't lye flat on your back, don't wear heavy blazers, or sunglasses. I try to keep my neck muscles loosened up all the time. Whenever I get tense or stressed out, it goes straight to my neck!!!! Then my Occipital Nerves get mad and they start to hurt!!!! I go for walks every evening for about an hour. I feel great and my head does not hurt during or after my my walks. But when I sit in a stationery position, like at the computer or watching TV, then my O.N. will kick in and start hurting.
Good luck. GOD Bless you.
