It wasn't at all what I expected.
The cannula insertion itself was not painful, but the pain started creeping in a few seconds later. At first, I couldn't touch the pod without eliciting sharp pain. Then, I tried to sit down. Nope, sharp pain. From that position, I tried to straighten up. Nope, more pain. After 5 minutes of that nonsense, I decided that the pain just wasn't worth the pod. I deactivated the pod, then proceeded to remove the pod. That was the worst pain of the whole experience. I had to work the adhesive off in small, 1/4 inch, sections at a time, all the while experiencing pain that had me almost doubled over evertime I tried to manipulate the pod.
As soon as the cannula came out, the pain just disappeared. Nothing, not even residual soreness remained.
Anybody ever experienced anything like that? This was on my abs, btw.
