I also experience blurry vision and shaking, along with pins and needles before I get a migraine around 1 to 2hrs later. It's called a migraine with an aura, if you need a better way to describe it to a doctor. I am afraid that I can not help you with how it connects to exercise though, sorry.

I am 37 and I too get blurry vision about 1 to 2 hours after I exercise.

I went to the doctor and he told me he thought it was either dehydration or a drop in sugar perhaps.

I too don't know the limit of when I should stop my exercise either to avoid getting the blurry vision because I do not get overly winded or short of breath. I do sweat excessively when I exercise.

I went to the cardiologist about 1 1/2 years ago and everything appeared to be fine.

I have let it slip though lately and it is happening more often. Next week I am going to an endochronologist (diabetes doctor) to see if its my sugar levels that is causing this.

I get extremely nervous after this happens and suffer from major anxiety from it. Usually I have some sugar (juice, candy, etc.) and it goes away but I don't know.

I will report back when I get results from doctor.

Hi All,

I too get the blurry vision where I can see sort of sparkling lights , only lasts for about 10 minutes at a time after rigorous exercise. Also comes with a slight headache, shaky hands and a need to have something sweet , surely this must be blood sugar related. Did your endochronologist have any ideas ??

Only been having it for about 4 months or so and it started from nowhere it seems.

Great to hear I'm not the only one living with these symptoms any insight is appreciated.

Cheers,
Brandon

I have had experiences of blurry vision about an hour after playing hockey. I relate to not knowing the trigger, but not shakiness. Last night it happened and the blurry vision lasted about an hour. The blurry vision gave me a slight headache; I don't really get headaches. The blurry vision went away, but I woke up a few hours after going to sleep feeling like crap, in a cold sweat, and eventually had to vomit. I've considered it might be dehydration or low blood sugar. I might have reactive hypoglycemia. By the way, I'm vegetarian. Anyway, I'd like to hear the one person's results, and anybody else's experiences, insights, etc.

Thanks,
Kurt

hmmm... I am 30 years present and I too am curious as to why my hands were shaking while I was drinking from my water bottle last night - during and after my netball game. It didn't last for too long but about an hour or so later, I then experienced a headache. I haven;t come across any professional answers as yet, but it seems as if blood sugar levels could be related? I will look into this further.

I also get blurry vision after rigorous exercise...no headaches though. When asked to describe the nature of the blurriness by my eye doctor, I had difficulties describing it. Now,, since I am experiencing it as I type this, I can say that it is in the top left corner of both eyes. There is no nausea or dizziness but it also occurs about an hour or so after intense cardiovascular exercise. This post is obviously old but if anyone has any suggestions/ideas, please reach out to me through hotmail - balpern@.
Thanks,
Brian

Similar to balpern, I am experiencing this at the moment. I just went jogging, and the lower left side of vision from my left eye is worst, though my vision is generally blurry right now. Strange that I can't see anything very well (including this screen), but I can make out what I am writing somehow. This is not my migraine "aura," which is more of a light-headedness and contraction of my sinuses than anything. I actually exercise in order to get rid of my migraines (guessing the increase in blood flow does the job). That and jumping rope work better than anything else I have tried (Maxalt is the only medicine I have found that works; sleep over night also gets rid of it). This is the second time in the last couple months when this has happened. Otherwise I feel fine at the moment. No shaky hands, headache is gone.

I am 30 and for the last (approx)4 years occasionally after exercise I get migraines. Not too often but around 5-6 times a year. I'd finish exercise then about 20 minutes later I'd get the 'aura' which will last for about 10 minutes. The aura finishes then the painful headaches of the migraine start - always lasting 3 hours, almost to the minute. If I know I'm going to exercise I make sure that I've had something to eat before (not too much so I get stitch) and drink an energy drink (Powerade). I also try to avoid bright lights, one of my triggers. It gets me down a little as I want to exercise more but because of the migraines I exercise a lot less than I used to. Would love to know if there's a permanent cure out there.
