Oh dear FG, I'm so sorry that you're still in pain.

Although a frozen shoulder is really nasty, I sure hope you don't have RSD. I've read lots in that forum and we have our own dear Ali who keeps us up to date on RSD/CRPS.

If as you say TOS has been ruled out, so maybe we can all make up a diagnosis for you.

How about :

BS = Bloomin' shoulder

Surely there are other diagnoses out there.
Any suggestions?
