I started with a red welt on my chest which has not formed a blister. Now I have red patches with watery blisters on both arms, wrists and hands. I also have two red welts with skin slightly raised in the middle on my buttocks. All these welts and blisters itch! On my fingers, I have small bumps, one bump has a red spot.

I am taking Benadryl and using Lanacane for the itching. I'm thinking I'm having an allergic reaction to something I ate while on vacation; maybe the trail mix snack.
