Most of the time, it is due to getting moisture trapped underneath the tape. to give an example, for us girls, we get artificial nails put on, if ANY moisture at all gets sealed under that false nail....instant infection!! to try and avoid this, make sure the skin in very clean and very dry before applying anything to it. for now, I'd give it a break from any tape in the area that is irritated to be on the safe side.
