I requested a trial with Dexcom and just watched some youtube videos of insertion. No one screams in pain but I'd really like to know how it feels. The unknown with these things freak me out.
FYI- I use the Animas One Touch Ping Pump (still a newbie with the pump) and I use the all-in-one infusion set and so far it's been completely painless. Hoping this will be the same!
