I started off with Graves Disease and, over time and with treatment, that went into remission. However, I eventually became hypothyroid.
With frozen shoulder all that I've read pretty much says that having diabetes increases your chances of coming down with this condition. Men get it for sure. I know someone with type 1 like me who has it.
All I can do now is keep up with PT to get as much movement as I can back, and stick with keeping myself active now that I'm back at it.
