Let me start by saying I am in pain everyday from head to toe, I am 64 & otherwise in good health. I am currently being treated by a Rheumatologist for cervical spondylosis, lumbar disc disease, osteoarthritis of ankle & foot and Achilles tendonitis. and am not getting much relief. What concerns me the pain which occurs at the base of my head, if I turn my head while lying down, I can hear crackle from that area & pain follows.
