@Lisa, I used to overlap adhesive areas…until I got a nasty, crusty, itchy, skin reaction on Christmas Day last year. So I do not overlap adhesive areas until it (1) looks better and (2) has had at least three days of no adhesive on it.
I’m told that each cannula placement needs to be two finger widths away from the last one, minimum. This picture shows my current arm rotation pattern. I use one arm per month, and am trying alternate areas (upper butt, currently) to add sites to the successful rotation list.
Prior to pod placement, I have to use alcohol and Flonase. I use Unisolve for soft removal. I immediately wash the site once the pod is removed and put hydrocortisone on it for a few days until the outline of the adhesive disappears.
