Mikaylar is correct. This is a very difficult surgery to recover from. I have had 3 rotator cuff surgeries one included a bicep tendon tear that also needed to be repaired. The sling that you are needed to wear is a pain. Therapy is long and painful, but it has to be done. I know longer have pain in either shoulder, but my range of motion in my left shoulder is affected...that was over 16 yrs. ago. My best wishes for you Mum, but be prepared for a long recovery.
