OUCH!

So- Jesse decided to go on a bike ride through some random path in the woods.... where he then took a break, and must have came in contact with a little (a lot!) POISON IVY! He knows what to look for~ but must not have been paying attention. It started with a little patch on his hand earlier this week. Then on Saturday, he had 2 patches (that looked like big bug bites) on his back... and now it's gone to a full-blown rash, up and down his back! He went into the dr today and he told him it is indeed poison ivy. He has some heavy duty stuff to put on, but the dr also said that it could take 10+ days to go away. Now- 10 days from now we will be getting ready to fly on a plane out of the U.S., so I certainly hope it's gone by then. He's itchy and even in a little pain... poor guy! Of course I am SUPER paranoid, so I've been cleaning and washing things (even though I know it can only be spread from the plant oils... but.....).
Anyways- if anyone has any poison ivy tricks, drop a line!
