Mrrzy, maybe the slang term is 'glass'? It is proteins pouring into the blood stream from muscle that has broken down, long unused muscle that is put under stress without being given time to heal. That's what I've been reading. There are other causes, but the over-exertion is the one that fits my brother's scenario.

A month or less ago, he had some professionals come in and take down two trees, which he then spent a number of days cutting up and storing for the fireplace. He was proud of how quickly he got it done.

He had always been active but of course, at his current age -87- he no longer was.

Turns out the nurse that alarmed my brother is young and new. She brought in paperwork that asked my brother what he wanted done 'in the event of his death'. I have been asked that question often in a doctor's office but never when I was in hospital in the middle of illness!
