strange things

I looked for conditions likely to cause constricted pupils, removed any that were unlikely based on your other symptoms, and came up with this list. The first thing I thought about was a vasovagal episode, and it may be, you were lying down, got up, and blood pressure could have dropped. A vasovagal response would produce most of the symptoms you described. The constricted pupils were listed by some sites as being vasovagal, others listed dilated pupils.

Generalized anxiety disorder
Generalized anxiety disorder is a condition in which a person has nearly constant anxiety.

Fainting (vasovagal syncope)
Before fainting, you might feel lightheaded, warm, nausea, a cold sweat, or have tunnel vision. (You can have a vasovagal reaction without fainting).

Panic attack
When someone has a panic attack, that person feels a sudden, intense fear that can't be controlled.

Hyperventilation
Hyperventilation is rapid or shallow breathing usually caused by stress or anxiety.

The Autonomic Nervous System, which the Vagus Nerve is part of, can have fluctuations in it's performance as well, and if you're afflicted with anxiety, even more so. The autonomic nervous system consists of a sympathetic and parasympathetic side.

The sympathetic prepares you for fight or flight, faster heart rate, suppresses digestion, dilates the pupils, raises the hairs on your skin (I'm sure you've seen an angry dog, the hairs on their back stand, they bristle, that's fight or flight).

The parasympathetic system calms everything down, constricts the pupils, relaxes the hairs on your skin.

Here's an idea of the complexity of these systems.

Be sure to discuss health concerns with your doctor. You can keep a diary of incidents, day, date, time, what you were doing (sitting, just got up, walking, etc), and a brief description of your symptoms. It may help you, or your doctor, understand if there's anything in common.

"One morning I woke up, and then walked out to the kitchen, felt nauseus, and I got sweaty on my head..kind of like a flu but it wasn't . Felt like all my blood was leaving my body. "

To me, this sounds like it could be vagal.

Recovery of everything by the time you got to E.R. wouldn't surprise me.

The sympathetic system dilates your pupils, so, one would think the parasympathetic system constricts them, but I read conflicting things about that.

"I have vision issues too. I have always chalked this up to anxiety, because I do get scared and panicked bad."

I'm curious about the vision issues, I was an optician, not for long, but went to trade school for it, worked for a year or so in the field before moving onto other vocations. But, the real reason for my interest is I've been plagued with visual issues myself. One is quite simple, a convergence reaction when startled, for some reason that's a natural event. I've also had ocular (visual migraines), and diplopia (double vision). I've even lost the vision in one eye, twice, but it's returned within minutes. I've been tested so much they'd need a shopping cart to carry my records, if they were still in paper. If you'd like to say what visual symptoms you notice, I'd be interested to hear.

Actually, tunnel vision is characteristic of a vasovagal response, especially since you said it feels like your blood is draining. The size and shape of your pupil does not condition anything but brightness. Cats have a slit for pupils, but they still see normally. My wife's grandmother, years ago, had cataract surgery and they seriously damaged her Iris (the colored part of the eye that forms the pupil). Despite having a keyhole Iris, she could still see.

If you're outside on a bright day, the pupil is as small as it can get, or fairly much so.

The following is from an EMT page on the value of constricted pupils for diagnosing a patient. Among other things, they mentioned:

"There are a few classes of chemicals that cause parasympathetic over-stimulation and, therefore, pinpoint pupils."

My point for including this is the reference to parasympathetic over-stimulation as a cause.

Look at this page, they elaborate conditions and medications that can cause it.
