Blurred Vision 3x Day

I have been told that what is "believed" to be my problem is Migraine with Aura.  I have been having these symptoms on a daily basis.  I've already had an MRI and MRA.  Everyday, I get episodes of blurred vision, where it feels like my eyes are crossed.  This lasts anywhere from 5-10 minutes, and I can have several a day.  It happens when exiting a shower or bath, standing up from bending over, and with every orgasm.  It's really scaring me, and is happening more frequently.  Is it really just Aura Migraines, and nothing to worry about?

Blurry,

Blurred vision is a common aura-symptom of "uncommon migraines."  I've only experienced it a few times in many years.

However, it sounds like you are describing double-vision (eyes crossed), not just blurred vision.  Next time it happens, close one eye and see if your vision is blurred (look at lights and see if they look blurry), if so then it could be aura-type blurred vision.  If it only occurs when looking through both eyes, it's double-vision.

You didn't mention pain.  If you're not experiencing a headache, it could still be silent migraines.  However, I'd find the nearest headache specialist neurologist (not just any neurologist, and definitely not a primary care physician).  I'd also schedule an appointment with an opthalmologist, and see if you can be referred to a neuro-opthalmologist.

The "triggers" you mentioned seem related to vasoconstriction and vasodilation.  Hot water in the shower/bath, standing, and orgasm all cause changes in blood vessel dilation/constriction and this could mean many things.  You should have your blood pressure checked when laying down and then standing (to check for POTS).  However, many migraine-type headaches can be triggered by showers and orgasm.

Thank you for all the info!!  
Yes, it's more of double vision.  I guess I really just have to deal with it.  They've done all the blood tests too, and nothing comes up.  (Which is a good thing too!)
