What is the scariest medical symptom you ever had?

[BrickPoet]

pain in my throat for 10 days

Gallstones

Heartrate of over 200bpm for a few hours.

I passed a large wriggling worm from my bottom. I am not joking.

Nose instantly blocked and my throat was closing up and I was struggling to breathe due to an undiagnosed nut allergy. Lots of other things going on at the same time. I really thought I was going to die.

Yikes! Im
having mine repaired in a few weeks to mitigate against this!!

First shower after c section felt very faint, light headed, dizzy, couldn’t see. I had to ring the emergency buzzer and all these midwives came running.

My iron was low. My first blood test post birth showed it was normal but they retested and it came back low. So was resolved but it was very scary.

Suddenly feeling detached from my body, trying to make myself press the emergency call button whilst sitting on the toilet after major surgery (removing part of my skull and adhesions on spinal cord). Then nothing.
Coming around with 5 nurses crowded in the ensuite, one with her hands wedged between my head and the basin. She just managed to catch me before I smashed my surgery site.

Pooing blood 50 times a day

Was Ulcerative Colitis. Had large intestine removed, got a colostomy bag now

Waking up in ITU not knowing what happened.

Turned out I had an acute kidney injury due to heavy duty antibiotics after a ruptured appendix, and I was placed in an induced coma for 2 weeks.

Oh wow. My heath anxiety is not liking this... yikes

Maybe this thread needs a trigger warning!

Ruptured bowel and gangrene.

Not serious but I used to be a big fainter when I was younger. That feeling of sweating and drifting towards unconsciousness is horrible

Perforated bowel which then developed in to sepsis. So so painful that I felt like I wanted to die.

When I couldn't breathe due to a pulmonary embolism and pneumonia.

When l got thrown under a bus by an ex.
Left for dead ( now disabled) he got jailed for attempted murder.
Been in pain ever since for 36. years

Humans are both very fragile and incredibly resilient, it's a strange paradox. Easy to see how we can overfocus on either end of this.

Depersonalisation for 18 months. I was on the verge of a psychotic breakdown.

And a lump in my breast that was ,thankfully, nothing to worry about.

My first ocular migraine.

No pain, no symptoms except flashing lights. Then I realised I couldn't read, the words on the page just faded away half way through. Then suddenly I was about 60% blind.

It was utterly terrifying, I thought I was having a stroke and about to drop dead.

Hemiplegia in 2 hrs. Terrifying.

On the other hand, the least scary symptoms I had was an ache in my shoulder and a tingling in my little finger.

I had a lung cancer. These were my only symptoms.

Scary symptoms and scary diagnosis don't always go together.

Jesus Christ

Goes off to the puppy threads....

Labyrinthitis

Acute episode of cholecystitis. Honestly thought I was dying from the pain, and even morphine didn't touch the sides. Remember being admitted from A & E to a ward at 3am and trying not to scream the place down. Awful awful pain. The sort that makes you question your sanity.
