Hi, was playing rugby a few days ago and made a tackle, my arm went numb after the hit didn t think anything of it as this happens sometimes after a big tackle, woke up the next morning and I can t raise my arm to the side at all I have full movement of my arm when its support but I can t raise it by myself at all there is also no pain, it aches a little in the muscle but not at all painful, lease help as its starting to worry me
