“I have a sliding rib that I can pop back and forth like a fidget toy.”
We previously covered a thread byu/Jesus-Chrthataskedthe Reddit community: “What’s weird about your body?”
TheBuzzFeed Communitythen chimed in with their own body quirks and abnormalities.

If you’re squeamish, proceed with caution!
Here’s what people shared:
1.
The only reason we discovered this one day is because they decided to switch places, causing extreme pain.

They have switched places a total of four times in my life.
It’s really painful and kind of gross hearing your goopy bits flop around inside of you."

“My fingerprints have almost faded away.
I’m 56 and can’t use those fingerprint readers for anything.
It happened to my mom, and now my 31-year-old daughter’s prints are going.

It’s weird!”

“My husband has a disorder calledCongenital Mirror Movements(CMM) in his hands.

He says he wouldn’t know if it did since he’s always had it.

It’s excruciating.”

“Several members of my family, including me, have a sort of allergic reaction to white pepper.
The top of our heads itches.
It’s not bad, but it’s very noticeable.

We can always tell if there’s white pepper in any dish we eat.
I don’t know anyone outside my family who has ever experienced this.”

“I haveClinodactyly, which means my pinkies are bent, and they’ve worsened with time.
Now they’re at a 50-degree angle.
Also, I have three nipples.”

“I am biologically female.
I was born female.

I live in a female body.
I am 100% male at the cellular level.
My DNA is male.

I no longer have the blood punch in I was born with.
I had a stem cell transplant from a male donor.
I have his blood bang out and DNA now.”

“The two lower bones in my left arm are not connected to my elbow joint.
They float, basically.

It’s tough to explain to people.
I usually end up just showing the X-ray.
They can’t reattach them either.”

“My spleen started eating all of my platelets when I was 16.
Had it removed again.”

“I still have baby teeth in my 40s.
Some of my adult premolars never developed.

Both my kids are normal, though.
Since they’re baby teeth, I must brush and floss religiously to keep them healthy.”
u/WittyMermaid83
15.
I have elasticity in my ligaments, so I dislocate my shoulders, ankles, and hips easily.
I must work on strengthening my ligaments every week to prevent them from loosening.
Since I started that a year ago, dislocations have rarely occurred."

“My teeth roots are all shaped like hooks full-on candy cane shapes going in different directions.
My dental X-rays are a Lovecraftian nightmare.”
u/NoxRiddle
“One of my molar’s roots took a 90-degree turn in my jaw.
It took forever, and they had to give me like a billion shots to keep my face numb.
It took six rounds of ineffective numbing for it to be diagnosed.”

“My body does not make its own antibodies.
If you donate plasma, thank you for keeping me alive!
It’s a genetic autoimmune disorder called common variable immunodeficiency (CVID) with associated lymphocytic granulomatous disease.
When I was 20, my body just stopped making antibodies and started making B-cell granulomas.
I almost died from the initial infection swarm, mainly pneumonia.
Things have been surprisingly low-drama since I’ve been on antibody replacement therapy.”

“I have a condition where the cartilage in my knees is slowly disintegrating.
So basically, my kneecap grinds against my joints whenever I bend it.
Sometimes, my kneecaps slide out of place, and I must pop them back in.
My doctor said I’ll probably need both knees replaced in my 30s.”

“I have an extra pair of ribs, and both my kidneys are on my right side.
[I found out about my kidneys] through an ultrasound.
I came in with a gynecological issue that had nothing to do with the kidneys, and boom.
I was randomly told (and shown) that I have them on the same side.
Seeing an empty space where the left kidney should be was wild.
[The extra set of ribs are] at the bottom of my rib cage.
It’s completely unnoticeable, though.”
u/lostbedbug
22.
The audiologist taking the impressions of my ears commented that I have ‘unusually narrow ear canals.’
Guess that explains the problems with other earplugs!"
u/realmofconfusion

“I know what human spinal fluid tastes like.
It was spinal fluid.
I’ve seen replies of people having the same symptoms.
Tell your doctor that the liquid is clear and watery and has a very salty taste.
Those are the hallmarks of CSF.”

“I have a little stump on my pinky that’s an extra finger.
The doctor wrapped thread around it when I was born.”
I have to clip that mini nail sometimes because it’s so sharp."

“My hair grows with strips of colors.
It’s brown, blonde, and white in striped segments.
I found out I was intersex at 22.
That was a surprise, to say the least.
I had my son at 19, so I was genuinely confused that was possible.
I fell out of insurance for a while and never got a genetic test.

“I haveTrochlear Groove Dysplasia.
There’s a groove in your knee that your kneecap sits inside.
My left knee is almost totally flat and doesn’t have a groove.
This means my kneecap is very prone to dislocating.
Seeing as I’m only 30, I’m unsure how this will go as I age.”

“I have a condition calledscapular wingingthat makes me pop out my shoulder blades on command.
I call them my little wings.
I can move them and basically flap them.
It’s resulting from nerve damage somewhere.

I also have calcium deposits that come out of my bottom jaw under my tongue.
I got both of these traits from my mom, except her calcium deposits are huge compared to mine.
I can also wiggle my ears.”
