Thanks for the advice.

Also forgot to mention that there is some nausea. Aside from the ache, my neck doesn't feel worse when I press it or move my head around. Does this rule out the cause being a neck injury? If not, how is the recovery procedure of a neck injury different to that of a TBI?

If anyone here knows of similar strange symptoms, I would really appreciate hearing from them.

Thank you for your help!
