Good! That will give you a few days to familiarize yourself with it before surgery.
Given the amount of pain you are experiencing right now, your ice machine could possibly help a little bit even before surgery. People will say nope, but mine helped my knee pain to go from excruciating to only miserable before knee surgery. It's worth a try if/when you can't sleep.
I am so glad you don't have long to wait until your surgery date! Soon your extreme shoulder pain will be just a distant memory.
Thanks W2R! I agree 100% that the ice machine would have helped sooner. Not sure why I didn’t think of that, since I experienced one at PT and loved it. Their machine cost around $2K and was huge so I didn’t even ask if there was a smaller and cheaper version for home use. Duh!
