re: Vaccine and “frozen shoulder”

Typically, frozen shoulder starts in one shoulder and heals with proper exercises in 8-12 months. Then it may do the same in the other shoulder, but not usually both shoulders at the same time, or even overlapping.

First shoulder happened to me in 2018. Thought for sure I had a torn rotator cuff, but Orthopedic Surgeon diagnosed it right away. Fluctuating levels of pain and shifts in the primary source of pain over about 12 months. Had two cortisone shots and did specific exercises as directed by orthopedic surgeon.

About a year after my left shoulder had healed, it started in my right shoulder. Didn't even bother going to the doctor. Knew exactly what it was and just did the same exercises as before. 12 months later I was back to normal. Very strange that it actually "works its way through" over 9-12 months. With either shoulder, if I had been arrested and had to put my hands behind my back, it would have been excruciating pain beyond description.
