I've been pumping for 18 of the 41 years I've been t1. The scar tissue is everywhere and I must change my set at least every other day now. I've got a lot of places I just can't go anymore, and I try not to go near a site within at least a month. I am short and not too big so there's not much available real estate. I was just wondering if you have a system and how it's working for you.
