Hey Amanda. Sorry to hear about the scar tissue developing. I was wondering - how much do you inject when you take insulin?
I know for me - when I was MDI (40 years - now on pump for past year) - that because I wasn't using large amounts of insulin to inject with (most was 6 units with Lantus morning/night - and then 1-3 units about 3 to 4 times a day) - maybe it helped in not developing scar tissue. I also rotated like you did - and became quite flexible with the rear end! I know we diabetics are prone to having tough skin - that is what I've been told by many medical authorities over the years. We are tough cookies!!! Like you my arms - looked like I was an athletic - but far FAR from it. I don't think it was because of having scar tissue tho' that my arms - legs looked like this - it's just the way I'm built.
I did have problems with scar tissue on my rear end tho' in my teens - it was gross when I would inject there - and it felt like I was going thru' dry tissue. Anyone had that feeling too? I had to basically give that portion of my body over a years rest - before things went back to normal - and the areas that had sunk in filled out again.
Again, like others have said - rotation is the key to scar tissue not developing. I have more fear of that happening with me now with using the pump and keeping the infusion set in for 3 days - and it being a larger diameter then the 32g needles I use when I inject.
