Curious what your pump sites look like after removing an infusion set.
I am 99% sure that I'm allergic to the cannula, and that I also find the adhesive irritating (I often find things like Band-Aids irritating, too). I've never seen another site in order to compare, though, and no doctor has ever seen mine, although my endocrinologist agrees that, from my description and from my blood sugars, I seem to have an allergy and we are trying different sets to see what works.
Usually when I remove an infusion set there is a bright red, raised area around where the cannula was, sometimes it stretches out and follows the path where the cannula was under my skin. This area is always very itchy. There is also a raised circle around where the plastic hub was, and often (but not always) a red ring around the outer edge of where the adhesive was and sometimes tiny hives underneath.
Also curious how long your sites last. Mine barely last two days before they stop working. Sometimes they only last one. My sites get itchy after one or two days, and stay itchy for a day or two after removing them.
I know some degree of bumps/irritation is normal, but I'm just wanting something I can compare mine with.
