I am a 30 year old female, only health issue are that I am low iron, low blood presure and low blood sugar levels. a few days ago, my vision went all blurry starting in the right eye, it was like I couldn't see straight just periphial. Then my left eye went blurry, after my eyes were fine, my left hand fingers went numb. Since then I have had a constant headache. Any ideas why this would happen or cause this?
That is classic migraine. Typically it comes on with stress so perhaps you've been worrying a lot recently. Sometimes it is difficult to pinpoint the trigger. The best standard relief can be obtained with ibuprofen or another anti-inflammatory.
I'm with Brian--sounds like migraine with aura. Do some reasearch on migraine and aura.
Apparently, some foods can trigger an attack. FYI, in my case, it's a bad back/neck, so finding the trigger can be difficult. If this is your first attack, you might want to go through the preceding 24 hours to look for anything suspicious, or stressful.
