A frozen shoulder is the most painful thing in the world. You cannot lift your arm above the shoulder - so dressing and showering is a problem. If knocked in the wrong place there is a spasm followed by a lightning shock which slowly recovers. You hold your arm in a sling postion for a time.

It is only temporary however and it lasts about 12-18 months. I worked through mine as I have my own business and can sit at a desk all day.
