I m 65 year old male and have had a stiff neck for nearly a year which wasn t caused by any accident. At times I also have a dull headache above and behind the left ear, which is normally a around a 2/10. The stiff neck and headache tends to get worse at night/early morning and has woken me up sometimes, but improves and eases during the day. I also have pins and needles in the left arm from the shoulder to the elbow for some of the day. I have also had four sessions of Physio, and this has given me a little relief at times but the stiff neck continues.
If you are having neck ache or stiffness with sensory problems in one of the Arms that would imply a problem with the nerve roots arising from the neck that go to your arm ... I would recommend an MRI Cervical spine to rule out cervical disc disease or any other cervical spine problem ... until then please wear a soft cervical collar while you're sitting or travelling or any time your neck is bearing the weight of your head ... and a simple NSAID for the pain and stiffness ... after an MRI you should consult with a Neurosurgeon
