Like "Since I am on the pump, I don't do the injections. I have an infusion set that attaches to the pump. However, I do have to rotate the areas where I insert them. I have to change them out every three days, so I just move from one side of the stomach to the other each time I change sites. I only weigh 110 lbs., but I still have some meaty areas, and it really is not painful at all. "
