Yep sounds like a migraine.

I have killer migraines. They start with i see squiggly lines in my sight, when they start i HAVE to take something right away if i wait 5 mins its generally too late and im hit with being unable to see anything, my hearing goes and my head goes numb and heavy and my head POUNDS. At this point nothing makes it go away only sleeping. But i usually have a lingering headache for days afterwards.

If this is the first time experiencing it you should see your GP.
