Where is my visa!

AHHH! Hurts!

Recently I’ve suddenly started to get headache. I don’t know exactly why it occurred. It hurts so much. And strange enough it occurs only the right half of my brain.  It starts with a strange feeling in my head and it becomes suddenly strong! And it lasts about an hour before it gets better. While it’s on my head I can’t even walk. I have to lie down and breathe deeply.
