I have no trauma or an accident so this pain is quite a mystery. Earlier in the week I had scout numbness started on the right which moved to the left and now on the apex of my head. On my right side about elbow level it's painful and it's hard to extend my arm without feeling pain. Lifting only creates more pain I can grab with my hand but even my grip is very weak.
A few years ago I was seen by a chiropractor for c4 subluxation. With therapy, acupuncture and exercises I was able to prevent surgery. Symptoms were a little different and they were on my left side (current symptoms are only on right). I did not have the scalp numbness either.
