Transported by ambulance to the emergency room due to orthostatic hypotension

My mother experienced paralysis in her arms and legs due to orthostatic hypotension and was transported by ambulance.
I think it was about a year ago.
I received a call from my mother on the subway on my way to work.
I received a call at this time, which is unusual, and I answered, thinking it was strange.
Mint, Mom's arms and legs are paralyzed and she can't move, so my young nephew was trying to make a call as instructed by grandma.
I was so surprised that I called 119 and then went back.
I'm so surprised that even now, as I write this, my heart is pounding.
I called the paramedic and went to the emergency room of the hospital where she was transferred.
I completed all the tests from the brain to the electrocardiogram, and they said there were no particular abnormalities, but I was advised to be cautious as it might be suspected of orthostatic hypotension.
Since I have also experienced feeling dizzy and spinning when I stand up after squatting down, I used to think that orthostatic hypotension was just a light dizziness or spinning sensation, and I never imagined that it could cause paralysis in the limbs.
After researching and looking into orthostatic hypotension, I found that such symptoms really do exist.
My neck became stiff, my muscles stiffened, and my whole body became weak, so I couldn't exert any strength, and I felt it as if I was experiencing paralysis symptoms.
Fortunately, there are no dangerous situations like orthostatic hypotension behind this time, so I am very relieved.
But I'm worried because I never know when the same symptoms might suddenly appear due to orthostatic hypotension.
If you have orthostatic hypotension, it would be best to be very careful and cautious.
Orthostatic hypotension can be accompanied by dizziness, headaches, and bowel sensations, so it would be good to pay attention to these symptoms in daily life.
Orthostatic hypotension occurs when the body's autonomic nervous system responds appropriately to prevent a drop in blood pressure and maintain stability, but it is often caused by unknown reasons.
So, I think it's best not to take my body's symptoms lightly and to keep a close watch on them.

I don't want to experience such frightening incidents caused by orthostatic hypotension again.
