strange eye sensations and confusion

Hey i need ur help guys! Yesterday when i was gaming on the computer, suddenly my eyes started seeing strange spots, i had a hard time seeing, like i had a bit of tunnel vision to. i felt a bit confused also and i felt slow.. after about 10min the vision thing got better but i still felt weird and very tired afterwards. i went to bed and i woke up fine 9 hours later.. i am 19 years old 74kg male 10% bodyfat, no other problems except parasites i believe.. good blood pressure, all vitamins, minerals in check. i do workout and eat healthy.. i thing ive got a blood circulation problem also because my hands and nose are constant cold.. is it possible i had a TIA? i hope not, i never had this before. but when i got it i did play the computer for 8 hours so i dont know, any help? thanks :) Tweet
