I have always gotten this after a migraine. I get about one or two migraines per year on average. For me, they go like this. 1. The aura, a flashing zig-zag of blindness moving across my vision for approximately half an hour. 2. The headache. This is unpleasant but not nearly as bad as some have it. I usually go to sleep for a while until it gets better. 3. The aftermath. I feel mentally foggy and more physically weak for several days, my sinuses are sore like after a sinus infection, which causes coughing, sneezing, or suddenly getting up or down and causing a pressure change to be painful.
