Poison ivy on my lip & on my husbands nuts 🤦🏻‍♀️

I’m pretty sure this is poison ivy on my lip. It’s numb and bumpy. Not itchy yet just feels really weird. My husband weed wacked our backyard on Friday & then we went for a romantic weekend in the city for our wedding anniversary... if ya catch my drift lol. He’s clearly got poison ivy on his side, shoulder & forehead and his balls are all red and itchy now 😭 this is awful. Any remedies for poison ivy?! Lmfao

Update: I’ve decided to make a doctors appointment. I have a cone biopsy procedure scheduled for the 16th and I don’t want to take the risk of it spreading into my mouth. 😩
