This explains the Flonase skin trick that I used to use for pods. It helped a lot at the time.
12 hour Claritin D every other day has been holding the itching and welts at bay for me. If I go too many days without it, my quarter sized pod welts come back with a vengeance. I don’t know how much of my issue is caused by my locale: Ohio River Valley, where we all end up allergic to air…and everything else.
And I apply hydrocortisone to every pod area immediately upon removal. Otherwise my skin scales up and I can’t use it for quite a while until it heals.
Do you ever use Flexafix tape? I reinforce my Dexcom sensors with that tape, and the tape adhesive doesn’t bother me. That could make a good base layer under the pod.
