When I wake up I'm ok, then after 1 hour my head starts to feel heavy and feels so weird, I feel something inside I don't classify as pain but agony, it is an agony feeling like I am being pushed down, also my eyes feels heavy, it feels like there is fluid circulating all over my eyebrows and make me feels bad, like I can't focus on something near me it give me a sick sensations. When I watch tv,the inside of the back of my head is constantly making pressure, when I walk it feels like the gravity is pulling over my head , my legs swing a bit it feels like I will fall.
What could be causing this, before I go to the doc.
Sorry for English.
