@jakedduck1, I apologize for the delay in my response as I am actually recovering from shoulder surgery myself. I just had a partially torn rotator cuff repaired and am now in the wait in a sling phase of my recovery. I was also just informed that the overall recovery period before I might get back to feeling "normal" could take up to around one year as well.
@jakedduck1, if your are comfortable sharing, what in particular was your physician concerned about regarding the seizures and your recovery? Is the involuntary movement that may occur when you are supposed to be immobilized in a sling?
