I just had a reverse shoulder replacement on October 13, 2022, so about 6 months ago. Best thing I did! I am a very happy patient. It was my left shoulder and I am right handed. I did not need much help, only 2 weeks just getting the immobilizer on and off. I could shower myself after 2 days and get dressed. I ordered before the surgery 3 big, very bid t-shirts and watched a video on line how to put them on after shoulder surgery. I practiced before the surgery to dress myself with one hand. The first week I wore a long skirt and no underwear... worked perfect. My surgeon told me to sleep on a recliner and that worked out also fine.
I hardly had pain. The first three days I had a nerve block and after that I only took once in a while (before sleeping) 2 tylenol.
Now I finished PT. I can lift my arm nearly straight up, I drive my car, wash my hair with 2 hands. No problem whatsoever. No pain at all. Looking back: it was 6 weeks a little difficult to have the immobilizer, but not a big deal. Prepare yourself is the major part. Oh, by the way: I am 85 years old!
