Interesting that you should mention this today; just last week there was a very similar posting on the Joslin Medalist Group - all members have been diagnosed with T1 for more than 50 years. Within a day or two there were a couple dozen members who posted experiences very similar to yours.
I have long know that carpal tunnel syndrome was one of the forms of “Autonomic Neuropathy”. And as you know neuropathy in its many forms tends to target PWD; I do have a trigger finger and for many years had carpal symptoms. I managed the wrist, thankfully, with a brace. Actually, there are four basic types of neuropathy but I won’t go into medical descriptions here.
I do feel for you and although my discomfort hasn’t been great, I know it causes MANY people much pain. The “good news”, if there is such a thing, treatments are available and from what I hear, they are successful. As I tell people with T1, THINK POSITIVE!
