I've had the op twice! Shoulder is now 100%! I had to have the op twice on the same shoulder because it didn't work well enough the first time.
You will be very surprised when you wake up and they ask you to move your arm! It does hurt quite a bit, but the pain subsides fairly quickly (2 days).
The physio after the op is most important. You have to be committed to the exercises, they really do help.
I've had frozen shoulders - in both shoulders but separated by about 3 months in onset. Mine eventually resolved themselves within a couple of years. I wasn't diagnosed at the time, though had had previous prediabetes blood tests. Didn't find out till much later that frozen shoulder (and other connective tissue disorders) can be related to diabetes. Fascinating how the body deals with all the excess sugar - but very painful to live with
I have had the op to free up scar tissue (adhesive capsulitis) from frozen shoulder. It was keyhole surgery and just a day case. Not too painful as I remember.
The most important thing is to do the exercises given to you by the physio afterwards as if you don't it will freeze up again.
I now have almost a full range of movement.
Good luck with your op
I have had 2 operations each time on both shoulders. First time I had manipulation under anaesthetic which gave me a bit of movement but in a few years I needed arthroscopic capsular release on both shoulders to remove scar tissue.The last operation has improved the movement and pain I have noticeably. I would ask whether the surgeon is planning to inject steroids to reduce inflammation during the operation as these can play havoc with blood sugar. Hope it goes well for you and gives you some better movement and pain relief.
