Was cleaning up some limbs with poison ivy all over them, three days ago. Today, I just noticed blisters on my forearm. Had the saaaame thing on my other arm a couple of months ago, after yard work. THOUGHT it was just a fluke. But NOOOOOOO! I'm allergic to poison ivy now. USED to never bother me at all. LUCKILY, it's not THAT bad. I used to have a Navy neighbor about 20 years ago who had to spend a night in the base Hospial because he had it so bad. His legs and hands looked like he had been hit by a flame thrower. What I have hardly itches or burns.
