Everyone is going to be different. In my case, I had home re-hab for 6 weeks and then at a re-hab facility for a little over two months. My soreness was similar to yours but I had decreasing levels and less consistency as time progressed. If I'm remembering correctly, I was off NSAIDs after two months.
Trouble sleeping was different - I had trouble getting into a comfortable position for about 3 months mainly because I am used to sleeping on my side where the surgery was done. I'm just now getting to where I can tolerate it. I will say that I don't experience pain as much as an uncomfortable feeling that wakes me up.
I finished formal re-hab two weeks ago, somewhat ahead of schedule but I have a long way to go with strengthening and a little way to go with range of motion. Internal rotation behind my back has a long way to go but other movement is fine but I'm still working to get it to match my other shoulder. 10 lbs both straight out in front and off to my side is fine. I'm able to lift 50 pound bags of potting soil and gravel example but I am very conscious about try to make sure my unaffected shoulder carries the most weight.
In summary, I feel like I'm back to normal most of the time. Occasionally I'll do something I shouldn't and the shoulder lets me know immediately to stop. I hope my experience helps you some. Hang in there with the exercises, they. make all the difference.
(I see my surgeon on Monday for the final visit - if I find out I'm doing things I shouldn't I'll update this note.)
Good evening, @mdgarnett What a joy to read such positive words about your post replacement journey. Congratulations on paying attention, being aware of your physical sensations, and living up to your commitment to hang in there with the exercises.
Just one note...in many states, you cannot drive with your arm in a sling. Might be worth checking it out.
I will be awaiting news of the update from your surgeon on Monday.
Be healthy and whole,
Chris
