I used to have a chronic pinched nerve in my neck that would radiate down to my arm/shoulder
i had the same thing last year for about 7-8 Weeks. The nerve of "C7" was damaged, but rebuild himself in the next 2 months, so the strength on this site came back to 100 %. I worked together with a physiotherapist who practized the "Dorn Therapy". The power in the right arm was in the beginning about 25 % of nomal, but after 2 weeks it started to get better and better.
Now just 1 year after this i´m stronger than ever before......(44 yrs, 9 months old)
