At about 1 am I very suddenly experienced these symptoms at the same time: Extremely severe headache (worst headache I ve ever had) Blurred vision, My right eye crossed inwards, Darkness in my vision, Nausea, Extreme dizziness, Dilated pupils with slightly different sizes (could barely see my iris), Bloodshot eyes, Extremely severe cold chills and shivering, The intensity and suddenness of these symptoms made me drop like a sack of potato s. It was very difficult to not black out. I was unable to call for help. This event lasted around 1 hour. I am 23 years old and I have had 2 TIA s this year, but this was different. I have no health insurance and am already up to my eyeballs in medical bills. I am still having trouble focusing on objects closer than 18 inches and my pupils are still dilated. Why are my eyes still dilated? What happened?
