Poison Oak...Ivy...or Sumac???

So a couple Sundays ago, Jeff and my dad went to put up Jeff's tree stand in the great Nebraska woods. Jeff came home...was a bit itchy...but typically is when he has been out in the woods. I also want to point out that Jeff ALWAYS wears long pants and long sleeves when he is out there, but that particular day, he did not. So...Wednesday night he notices some "bug" bites. They were COVERING the bottom of his bicep...the part of the bicep that touches your chest wall. He also had TONS of these "bug" bites on the opposite side on his neck. Poor guy. I thought...WE thought it was attack of the killer spiders or something! By Friday he had done everything to try to get the itching to stop...LITERALLY EVERYTHING that we knew. It just kept getting worse and worse. Finally Friday afternoon he decided to go to the doctor...it was poison something or other. Oak...Ivy...or Sumac. Hard to tell...but they all act about the same, so the good doc gave him two oral prescriptions...an antihistamine and a steroid. He is to take these for four weeks...and the rash won't go away for 3 weeks! NASTY!!! It went from being bumps...like bites...to his whole arm being swollen, red and GROSS looking!! It kept spreading....today it is still all over his bicep and now all over the chest wall where his arm touches. It has also spread around his neck and he is starting to get them on his other arm as well. He uses special creams, but he also has been pouring bleach on it...OUCH! He says in general it itches and burns...and just feels awful! He will NEVER go back to the woods with anything but long sleeves on, and he will NEVER touch that branch that has it again. He went back last night with Jake. He checked out the tree stand...and sure enough, he had to have hug the vine that this poison "oak" was on because it runs right up his tree stand. He isn't going to move it though. We will see how that goes. Dad didn't get it...but dad says growing up they had a fence that went through a poison oak patch and when the fence needed fixing they sent him in because he was the only one that never got it....so dad could have touched it, but he didn't get it. Lucky duck...Jeff is pretty miserable. Here are a couple pictures...but these were taken before it got that bad. For a few days it drained horribly...pus all over the place. ICK! He has thrown away quite a few shirts. Poor thing!!!! NOTE TO SELF....WEAR LONG SLEEVES WHEN IN THE WOODS!!!
