Yes, I'm very sensitive to it. Back in the early 2000s I helped a friend clear some brush/scrub from the backend of his property. I wore a hat, long sleeve shirt, gloves, and shorts.
By next evening my legs were covered with it. It lasted about ten days, despite using poison ivy soap, calamine lotion, and some home remedy concoction the wife said they used on the farm as she was growing up.
It itched terribly, and I kept scratching it. I wound with a series of very noticeable scars and pot marks, particularly on the left leg. A few years ago while standing in a concession line at a Reds' game, an older gentleman with a cane behind me asked, "Where were you based, and when?" Turns out he was a Vietnam vet who mistook my scars for shrapnel wound scars.
