Hives/rash?

I’ve been on 0.25 since sep 5th. Monday was my second week in my second month taking it. Last night I started to develop a rash/hives on my left shoulder…

Now I was at my brother house last night, happened within an hour of being there ON HIS BED. Turns out he has a HORRIBLE mouse infestation. I messaged my doctor about that and they told me hydrocortisone and Benadryl. Didn’t even cross my mind that it could possibly be from wegovy… so now I’m calling again tomorrow, first thing in the morning.
