Due to long term posture issues, long hours of desk job I had developed para spinal muscular spasms, there is pain in the cervical spine and shoulder bone whenever I try to stretch it. I visited a doctor and was under medication for a month, even though it slightly improved the pain never went away. My cause of fear is, the pain sometime effects the back of my head as well like a momentary spasm inside for a couple seconds. Please tell me whether progression of cervical spondylosis cause such pain in back of the skull as well. I'm worried If this is unrelated to my neck issue...
