I thought I would add a little update. Yes, he did go to the hospital. Last Sat night he couldn't sleep because his arms were burning so bad. He went to a 24 hr CVS (at 2am. I woke up @ 4 & noticed he wasn't in bed) & they sent him to the hospital. They gave him a steroid pill. He also had a follow up this past Wed with his doc & he now is using a steroid cream. We're not sure if it is poison ivy or oak, sumac. He told them (the doc at the hospital that his friend had poison ivy in his yard (that's what he thought), they never corrected him & said it was oak or sumac. So we don't really know.
