I've had not one, but TWO frozen shoulders! I had never been told it was a fairly common diabetes complication until I was diagnosed with the first one. With the first one, I chose to treat it with physical therapy, OTC pain relievers, and patience. It got better very slowly, but after a couple of years was back to normal. With the second one, I did not want to go through all that again, so I chose surgery and physical therapy. Three years after the surgery, I still do not have full use/extension of that shoulder. Hindsight being 20/20, I wish I had not decided to have the surgery and just endured it as I did with the first frozen shoulder.
