I love to wear leg sites. I have really great absorption with them, and they are really comfortable for me...most of the time. However, I've begun to use my legs on a more regular basis and I am finding that the sites are really causing some problems. I use the silhouettes (17mm) and IV 3000. I insert the sites and tape it down, but sure enough, after a day or so, my leg starts to get sore and red around the site. It is particularly bad around the end of the cannula under my skin. I always wipe everything down with alcohol, and I always wash my hands prior to putting a site. Is there something that I'm not doing?
