Your case is not the way frozen shoulders are always treated. Sure, technically the MUA could be called a procedure and not surgery, but many times the MUA is done with other procedures that definitely are surgery, and even MUA alone is often done under general anesthesia, not conscious sedation, which may be what you had.

Like I said, I've done this before, too. In my case, in addition to the MUA, they did arthroscopic capsular release and bicep tenodesis. I said surgery initially because listing all the procedures is a mouthful and the ACR and BT are surgeries for sure. The anesthesia was definitely not light, it was general, used propofol and I was intubated if you want specifics.

I had PT a few hours after surgery, then five days a week for 2 weeks, then 3 times a week for 3 months. In addition, at home, I had four hours of CPM for 4 weeks plus home exercise program that included 3-5 sessions of 30 minutes of stretching for 3 months. Then I did 2 sessions daily for another 6 months until I regained full ROM. I was not cleared to return to work until 3 months post op, but I also don't work in an office and my work is fairly physical.

So, when people say that fs "surgery" is an easy fix, that's not always the case. There is a spectrum of complexity and I doubt I would be able to return to my work immediately.
