Hey /fit/

I've got a weird problem, maybe one of you has heard of this.

When working out, especially one that really gets my heart going, I start to see this black cloud over the bottom of my vision. This goes away as soon as I calm down (start just walking, etc). However, there are two little black spots in my vision that stay for ~20 minutes - they are in the lower corners, on the nose side, and appear when I move my head.

I've never heard of anyone else having this, so I wonder if I should see a doctor or not.

you're blacking out. It's happened to me a couple times after running or getting up too suddenly, I'll lose my vision for a split second.

I believe it's got something to do with iron, but I don't remember.

I get the same thing. I've heard it referred to as 'black flies' which described it perfectly for me. I'd get it while working out or doing a sport then when I rested, they'd go away but return the moment I got back into action. Shit sucked, it was always worse when I got incredibly overheated as well.

This used to happen to me back a few years. Do you have really low blood pressure?

Do not fuck around with such symptoms. Your eyes are simply outgrowths of your brain, and if you are not getting enough O2 you may have a structural problem. Do you live in a country with doctors? Might want to have one check you out. An aneurysm is not as much fun as it sounds.

lack of oxygen.
Watch the vid, but shut down the audio, it's a horrible noise.

Anyway, that happens from time to time, people don't get enough oxygen in the brain and just black out.

OP Here,

If I'm blacking out, I must be really weak. Either that or I'm really good at pushing myself.

Nope, pretty normal blood pressure.

Well, I might go see a doctor (living in America with health insurance, since you asked) because of that, then. I do sometimes also get those "tingles" from lack of oxygen in my limbs if I push myself way too hard.

i get severe headaches when i lift, but not during cardio. my doctor said that my blood pressure is low and that, even though i drink assloads of water, i should drink more.

so try drinking more water? and yeah go to a doctor.

not OP

So the fact that I have a giant cloud of floaters and spots covering my entire vision field constantly is bad?
You know, like when the TV is just displaying that black and white dot crap noise

OP here,

Lots of people here are saying "lack of oxygen". While that may be true (makes sense), it also doesn't make much sense. In cardio workouts like this, I start breathing heavily (like anyone), but I have decent lung capacity (I used to do marching band), so... should I try controlling my breathing when doing these workouts? Fast? Slow? Deep? Shallow?

People have floaters naturally, but if there's a HUGE amount of them, and you see them all the time, you might want to see someone.

lack of oxygen doesnt always mean your cardio is bad. it could mean the blood just isn't getting to your brain, or the oxygen isn't diffusing into the blood to begin with

Sorry about bumping an old thread, but any of the night crowd (EST, it's night for me) got any more advice?

Actually I've had that also during high-intensity cardio workouts and I freaked out thinking it was glaucoma, so I went to an eye specialist who referred me to a neurologist and the diagnosis is that it was migraines with aura.

It's very much possible to not (or only very rarely) get the actual headache, but what you're seeing is the aura. You can look it up on wikipedia, it explains the different phases of it pretty well. The trigger for me is high intensity cardio, so it sounds like your trigger is the same as mine. My aura is bright, with something that looks like lightning stuck in my field of vision, but pretty sure black clouds are just a different type of aura.

I have a lot of "floaters" in my eyes. Came out of nowhere when I was like, 16 or so. I went to an eye doctor, and they didn't do shit.

Sorry, I'm not sure what the issue is, but I'm here to tell you, that sometimes, even doctors won't do shit for you.
