In August 2011 I had a severe dislocation of my shoulder as well as a small fracture at the head of the humerus I was also told that the radial nerve weas overstretched resulting in below elbow paralysis. I have about 50% return of use below the elbow. I was told that it could take at least 3-6 months to heal. I feel that the main problem stems from the elbow area. Would Vit b12 help in the healing ?
