Hi Lynn-Marie. Has anyone tested the possibility that it could be something as simple as a pinched nerve? My arm was asleep all week & I was starting to feel it other places in my body - my husband gave me a massage yesterday & VOILA!!!!!!! found a very painful spot just under my neck on my back - there was even a little hump - he worked & worked on it - went very deep (even though it hurt) & my arm has almost totally "woken up".
Hope this can help. . .
