Good afternoon @forge55. I'm glad you made the decision to become a Connect member. First off.......this forum is designed to make it possible for folks to learn by sharing their experiences and building knowledge about a condition that comes with many questions and concerns.

So.....let's tackle the driving issue first. Yes, you will be able to drive very well after RSR (reverse shoulder replacement) surgery on your left side. The only thing you cannot do is drive while you have the "immobilizer" on and that might be about 6 weeks..

And.....next.....yes, it takes longer to recover from RSR than from rotator cuff surgery. If you were to look at the surgical "tag" in your shoulder from the rotator cuff repair, you would see that it is only about an inch square. RSR involves removing and replacing bone in your arm and your shoulder. Bone comes with lots of other tissues like muscles, ligaments, and fascia.

Just so you know how I learned this, I have had four shoulder surgeries, including 3 rotator cuff repairs or attempted repairs and 1 RSR surgery. I must tell you that I was surprised at the moderate levels of pain I experienced after the RSR. I remember going out with friends for dinner 3 days after surgery which was on my dominant side.

What will make a difference in the outcome of your surgery? Choosing an excellent surgeon who can make sure that the reverse elements fit perfectly in your shoulder area. It is also important that your surgery arm doesn't end up being longer than your other arm. Mine is a little bit longer and I am now used to it.

What else matters?
PT......my physical therapist discussed and reviewed the therapy program with my surgeon on a regular basis.
Ice..... several times every day and an ice machine is the best element. I didn't have an ice machine so I froze water bottles and used them.
Sleeping comfortably while protecting your shoulder which will still be in the immobilizer. I didn't have a recliner and used a wedge with some pillows. I also
created a sleeping garment that came down over my head and shoulders. Button it up and don't put your arm through the sleeve.
A positive attitude which I had after two rotator cuff failures.
A commitment to comply with recommended exercises. You are the winner then.

Please let me know if you have additional questions. I do not qualify to respond to the amputation problem and yet I am sure you will figure it out.

When do you think your surgery will be scheduled?

May you be safe, protected, and free from inner and outer harm.
Chris
