I've tried it on the back of my arm and have knocked it off from hitting doors too. I've thought about wearing a wrist sweatband over it. There's a lady that makes bands for this but I think she's doing it only for kids. Her site is bands4life.net. I haven't checked out the site as I keep the pods on my stomach, upper and lower, and my back. I've never tried it on my legs. I don't think I'd try it during the winter.
I've read all the Goo Gone comments and can't bring myself to try it. I've read the Goo Gone ingredients and the emergency procedures talk about flushing for 15 minutes whether it's on your skin or in your eyes. I don't have much of a problem with the adhesive. I do have marks on my skin and will probably for as long as I use the pod or even an infusion set should I ever choose to change pumps. I have the same marks from my CGMS. It's the life of a diabetic. I don't ever plan to wear a bikini again so I'm not much concerned about it.
I have had bad pod sites that hurt a lot. I had one just this week. I changed the pod after 24 hours because I could feel the insulin going in every time I bolused or the basal was injecting. I must've hit a nerve. Even the cannula hurt. You can pull the insulin out of the pod. I've never done it after wearing the pod for a period but I've done it when I've had a bad pod before or just after starting it.
