Back in the last century I used to get tags - lots of them - At one time my GP was cutting them off as I was snagging them and bleeding several times a week.
Now that they have deigned to tell me I am type 2, I have been able to deal with them by reducing my intake of carbs right down, but I have always had problems with carbs. These days there are no more tags. Not one, though lots of tiny scars.
As you are type 1 there is a lot more to consider, but I strongly suspect a connection to diabetes than to any other medical condition.
I'd have much rather have had an earlier diagnosis than bits snipped off.
