Hey-Injecto!!
"Pricking 10 times a day" Man, that's a lot of blood, I'm not surprise your fingers are calloused, even for a type 1, don't you think that's a little excessive? why don't you give the fingers a rest, and try reducing the number of times you test, I certainly don't think this is a norm, over 4 years I've been pricking my fingers, can't say, I'd had this problem, for starters, I never used my thumb or index fingers, I consider these my workers, the other 3 that's OK, I test only twice a day, no hardness to my finger tips, whatsoever, was this recommended by your doctor when you were first diagnose?
seems strange to me, let us no how you get on, must be sore trying to hold-on to things. (Must reduce those pricks now)
