I just had a reverse shoulder replacement 6 weeks ago. I am still sleeping in a recliner - not too bad. I put down comforters on it. One on the back and seat and another one on the seat and footrest. They cover the armrests as well and it feels very comfortable and soft. I am since Monday allowed to sleep in a bed. I tried, but it is more painful and not as comfortable as the recliner.
My experience is: I hardly had any pain. I got a nerve block for 3 days and the first day some extra meds. After the nerve block was finished I only took once in a while 2 tylenol. The PT gives me now some soreness, but nothing compared to the pain before the surgery. I am a happy patient....
