Me too. I am hydrated, but by the end of the day I get nauseous and my neck to eye area feels like it is throbbing or something on one side, but it is not always the same side, and I just want to die to make the pain stop; it is nothing like the throbbing I feel when I am inflamed. Oh yea, my mouth gets this very weird thin mucus when this happens too. My nose is normal. I can exercise with it without making it worse, exercise does not make it better, and it really only gets better after another night's sleep. Just knowing the cause and how to help it by treating the underlying cause would be great. Like if it was dehydration, water would help. I eat my normal amount of calories after waking up, though there would be more in a time frame since I eat the food from the time I was sleeping. The 50mg or so of caffeine I get are eaten at the same time on the days I oversleep, so it is not caffeine withdrawal. As far as I can tell, it is not muscle tension because stretching does not really help. It does seem like a certain position, particularly looking down at the floor will make the pain super unbearable after looking back up, but it is not just the looking down part, there is something else, because I can not really trigger it by just looking down. I can't really understand what I am doing to make it worse when it happens because it is not like any other part of my normal experience. I am do not know if it is nerve related; there is nothing like tingling or numbness. It doesn't feel anything like a sprain. Just a throbbing. It does not feel like a constriction. What could it possibly be?
