My pump tubing has officially been hooked to every door knob in my house today...lol. Well not really, but at least 5 times and once on the arm of my patio chair. It's amazing how durable it is. I do have a question, after the last assault I did have a little blood under the site, but everything was intact. So I bloused for lunch and sure enough the blood disappeared. Was that wrong of me? Should I have changed the set? I was being stingy with my insulin...I just changed it last night and I was still fully loaded. Just thought I'd ask.
