Are you insulin dependent ? If so, what type of insulin(s) are you using?
The reason I am asking is that I had huge problems with arm, shoulder and leg pain.
I discovered almost by accident that glargine based insulins are known to cause myalgia (muscle pain) in a small number of people. Not much help if you happen to be the 1 in 10,000 !
Persuaded my doctor to let me try Levemir (Detemir based insulin) and all my muscle pains went away.
Lantus, Abasaglar, Rezvoglar, Semglee and Toujeo are all glargine based.
