There's no poison ivy but I keep getting it
...or a rash exactly like it. Tiny little oh-so-itchy blisters in singles and line-shaped clumps. I've had PI many times as a kid and have definitely learned to recognize it and avoid it. I'm certain there is none growing in my yard (and never has in the 5 years I've been here) and don't see any around the fences in neighbors' yards although there are a ton of weeds along the fence on 2 sides. They are all plants I've handled before with no problem. Nothing that looks like poison sumac out there either. I haven't been anywhere near PI since last year while camping. None of my tools have been exposed to PI. So I really think it's coming from some other plant although the rash is identical.
What could be doing this? I mowed Monday and started breaking out later that day, with new blisters showing up today still. Could I suddenly have developed an allergic reaction to one of these?:
pink oxalis clover
elephant ear (Colocasia)
English ivy (Hedera helix)
That's what I can remember touching within the past week but if you know of something else that can cause a rash identical to PI please say so, it could be out there & I'm just not thinking of it.
One other thought I had was that I was handling leaf litter. Could PI leaves have blown into my yard and still have urishiol on them? I also threw out those black walnuts (from another post) and since the carboard boxes no longer had bottoms, I touched them a lot.
