Aleo, it was so great to finally meet you in person today!
My mom's sunburn trick, which always works, even though it makes you smell like a salad:
1 cup white vinegar
2 cups water
a lot of ice
soak a washcloth in it, wring it out, and place it on the burn. Repeat whenever the cloth gets warm. I know I read some smarty-pants scientific-y article about why this works, but it was a long time ago...
I hope you feel better! Thanks & kudos to all of you out there working it today at the yard sale!
This is EXACTLY what my mom did.
