My head hurt really back on the left-back side of my head in the morning, after maybe 1 to 2 hours after I woke up, and abit later like 10 minutes after I started experiencing the headaches, I felt like throwing up, but nothing came out. Also for a week now or something in that direction, my vision has not decreased, but I find it really difficult to focus on reading small text (like books and continents of food products). Ohh and I might want to add that before the headaches my right eye had these pixel like formations blocking my vision. I went to sleep for a couple of hours and the headaches seem to have gone, though something still seems to be stuck in my chest.
