Im 3 months into C5 PALSY, my story sounded similar to Tim's. starting with no movement in my right shoulder and arm I now have full range of motion but my rear deltoid is still not firing at all, and still have some weakness in my bicep. My question for any of you is do you have a tightness where you have the palsy? My shoulder feels like its held down by rubber bands that always wants to force it back to its resting position. My arm after I lift 5 pounds 10 times feels like i just did 100 curls with heavy weights, the arm becomes very tight. Thank you and good luck to all
