As a person with an unexplained allergy that causes me to look like a toad and itch after napping in a field of nettles from time to time, I find these weird allergies so very relatable. Really, you can never know what your not-so-loyal body will throw at you next sometimes! Are you going to have an allergic reaction to pollen that comes from trees that are merrily spread all over the location you live in? Is it going to be your own sweat, for chrissakes?! The sun?? The smell of your significant other?!? Really, body, sometimes you outdo not only yourself but the fruits of our wildest imaginations, too, with these unusual allergies.

Anyway, this is our list dedicated to the weirdest and rarest allergies ever documented. If you have any of these, we feel truly terribly sorry for you. Even if it’s something as ridiculous as cockroach waste or showering, we do understand how hindering these extreme allergies might be in trying to just go about your day. Hopefully, though, you are an allergy-free person, and these weird food allergies (well, not only food - you can literally be allergic to everything) listed here will cater to your scientific curiosity rather than the hope of finding your mystery ailment listed here. If it’s the curiosity-feeding part, you’re in for a definite treat! And if you thought that people are basically allergic to just oranges, peanuts, and shellfish, your existing idea of allergies will be trampled to dust. Not to spoil the fun, but, among a myriad of other things, you can also be allergic to your own child. Your. Own. Child!

So, ready to check out the curiosities that we’ve gathered in this list? If so, scroll on down below and have a look at these highly unbelievable yet very true allergies that people have. And, if you have any words of condolence to those actually living with these sad allergies, share them in the comments section.

If I hold a power tool or even jog, my hands swell up. I never thought about it being an allergy.

Wth. This has happened to me too, with a power tool & a push mower. My hands swelled up and itched really bad. I had thought it was because my hands & fingers are so small lol🤷🏻‍♀️Now that I think of it, I used to get itchy and swelly all over when I used a riding lawnmower. I always thought it must’ve been the proximity of all the cut grass concentrated in the bag on the mower that was doing it. I can drive a quad and just my hands bother me a little bit from the handle bars, but it doesn’t vibrate like a mower, the seat is thick & comfy and there’s lots of shocks absorbers on it so it’s a lot smoother ride. Hmmmm. I guess I’m even weirder than I thought 🤔

I have this, but not too bad. Especially when on a bumpy mountain bike path, my hands on the vibrating handlebars get really itchy and a little swollen. Never realized what it was until I read this.

When I was growing up I remember whenever I would mow our lawn the palms of my hands would itch like crazy when I was finished. Apparently it was from the vibration in the handle. I didn't know this at the time but realized it many years later. It wasn't because I was allergic though.

You can not be allergic to vibrations or to anything that is non-organic. You might be intolerant or have a reaction whose SYMPTOMS are like an allergy, but it's not an allergy.

There is sometimes a very very low/deep sound that I hear in my neighborhood that makes my skin crawl and makes me nauseated. I don't know what it is or when it is but when it shows up it makes me feel like it's a kind of torture and enemy would use on its victims

I have this and never considered it to be an allergy, but it’s not bad. I have road motorcycles since I was a teen (I’m 42) and had times when I had to get dropped off at a gas station for my friend to go home and get his car because I couldn’t tolerate the itching anymore. Then I learned he switched pipes and he had to switch back. Been married since 2003 and I can immediately tell if my hubby switched pipes without telling me, he also has had to switch pipes for me. I also can’t tolerate using a rototiller because the itching and discomfort is so horrible.
