Are you putting Calamine lotion on the affected areas? It'll help. I can't identify whether or not that's poison ivy but I've had two simialr outbreaks of blistery, itchy rash that continued up the insides of my arms for some days before new ones stopped appearing and figured it must have been poison ivy.

Poison ivy attaches to trees with a fine network of thin aerial rootlets, resulting in a very hairy looking vine. This vine does not look like poison ivy at all.

I am not sure about poison oak, but one might guess they would act similarly.

Maybe oak then but the leaves are oily and three leafed. Certainly looks the same as google images of poison ivy leaf and poison ivy vine. Theres a pretty significant vine wrapping all around the tree. Oaks don't do that on their own.

Here's another photo

Looks like poison oak - if you had an in focus close-up of a leaf cluster we could tell for sure. There is a product called Tecnu that I remember working reasonably well to deal with the skin reaction issues back when I lived on a property with poison oak.

Soap and water should take care of your saw.

I had a case in the early 80's bad enough to send me to the ER for a prednisone shot - my eyes were swollen shut!

Good luck!

I googled pictures of poison oak vine and they certainly are very smooth looking, similar to your picture.

I stand corrected, it does appear to be poison oak. For whatever reason, I thought poison oak only grew west of the rockies. Considering my allergic reaction that fits the timing of hacking at those vines, I think it's safe to assume whatever it is, it has that Urushiol in it.

I've been using cortizone, and I bought that really expensive $40+ Zanfel stuff which really helped on the blisters.

i cant even tell .. from your pix.. if its LEAVES OF THREE ... and in LEAVE IT BE ...

I DEALT WITH SUCH ONCE..

created my own full body hazmat type suit ... long blue jeans ... taped to work boots [what nut cuts trees in flipflops???] ... long sleeve shirt.. again taped to rubber gloves ... ...

and then.. i cut at the ground.. and applied 100% roundup to the cut ... and then i cut it.. as far above as i could.... and left it all hanging in the tree ... riddle me this batman.. why does it need to be pulled down????

and then put all the clothes.. sans tape into the washer on high heat and heavy bubbles ...

and then spent the next 3 years.. cutting every sprig that popped out of the ground.. and hitting it with roundup again.. until it finally died ...

and then i found out.. it was an underground vine.. as big as the thing going up the tree .. and it had the ability to compartmentalize the killer .... dying back only so far.. and then sprouting again ...

eventually i won.. but for the idiot birds who continue to plant babes all over the property ...

i got quite a chuckle over your manly parade.... lol ...

Ken, you crack me up.

Sorry the picture is bad. I have to take the photo from 7 feet up to clear my fence, and I don't want to get too close.

It's an iPhone as well. First those leaves come off of small branches coming off the vines. The oak leaves are shaped and color significantly different.

When we were younger, a buddy and I were out fishing on the Mississippi River. We had to make a fast run to a nearby forested island for a bathroom stop. This island must have been named poison oak island, because not long afterwards, both of us were covered in poison oak (this was right before I was leaving for Canada on a fishing trip). I had it in every spot imaginable. Don't mess with any of it...I haven't had it since and hope to never have it again. Ugly stuff.
