Hello,

When did these symptoms start?
Just out of the blue or can you recall anything that may have set them off?

Could it be a repetitive strain injury of some sort, or have you ever had whiplash or a head, neck or shoulder injury?

I'm wondering if it might be muscle spasms, or thoracic outlet syndrome {TOS}, or possible a cervical spine issue.
Have you had any x rays or a MRI to check the c spine?
