Recovery from reverse shoulder replacement

What are others experiencing after a revere shoulder replacement?
I am 3 weeks post op today from the surgery. I had one Physical Therapy session with only passive range of motion activities. I was cleared for driving as soon as I was not taking pain medicine. I quit hydrocodone 5 days after surgery. My sling was never an immobilizer like I had after rotator cuff surgery. It is just a cloth holder to keep my arm close to my body and take the weight off my shoulder.
I am doing pendulum and swaying exercises 5+ times a day and bending my elbow. I start more active range of motion exercises next week.
I wanted to write this to give people encouragement if you are going to have this surgery. I needed a little help the first few days. I cannot lift anything that requires two arms, so heavy pans, etc. I have been showering, dressing myself, washing my hair, cooking, driving since 5 days post op. I am 74 years old.
One thing that might have helped my recovery. I went to physical therapy for 6 weeks before surgery to strengthen both shoulders.
Here’s hoping that all of us have successful outcomes and restore our function.
