Hi everyone, I have been reading the message boards for about a year now, my son was diagnosed in September of 2010, but I haven't posted too much yet. I have just been learning and getting support from all of you, thank you for that, it is great to have a place to go. I am finally just getting "comfortable" with our new normal and feel like we are starting to get the hang of things. We had a difficult start and about one month ago we switched out insulin from humalog to novolog and things have dramatically improved. He was resistant to the humalog and it was quite difficult to control his blood sugars before the change. He has the Animas Ping for 7 months and we are using the Inset 6mm. Then today after I removed his site, he had a lump under the skin where the catheter was about the size of a pea. It didn't seem warm or red, and it didn't hurt him...until after I asked if it hurt, so not sure about that one. Nothing leaked out of it, and the site was in for three days. Has anyone had any experience with these lumps and have any advice to offer? Thanks!
