Ouch! Emily's eyes swelled up overnight after contact with poison ivy

When you're ill, you can always rely on your family for a little bit of comfort and sympathy, right?
Well, not always. One young woman found this out the hard (and very public) way.

Emily Petrozza, 21, had noticed a rash from poison ivy - a climbing plant found in North America which secretes an irritant oil - on her arm, reports BuzzFeed News .
Days later, she found "little red bumps" on her eyes, but when she woke the next morning she couldn't open them at all.

Emily took a photo before the swelling got too bad

Bursting into tears at the sight of her swollen face in the mirror, she rushed to hospital.
NBC reports that Lauren heard her sister crying while she was still half-asleep. Emily went to a walk-in clinic and a friend shared a Snapchat photo of her severely swollen face with Lauren.
Deciding it was "too hilarious not to put on Twitter", Lauren decided to share it with the world.

And it's since been retweeted over 37,000 times...
"I think it’s funny. I thought people in my town would get a kick out of it," 17-year-old Lauren told NBC . "But I guess everyone else did too."
At first Emily was upset the photo had been shared, but she managed to see the funny side later on.

Other people have been sharing their experiences with poison ivy in solidarity with the poor girl.
And they look equally as swollen.

It's since been reported that Emily's swelling going down and she's on the mend.
Hopefully there'll be no more poison ivy in her future.
