I am male 33. I have been experiencing a pain in my head and unbalanced feeling when walking like I'm dropping to my side. I have had a CT scan brain two months ago for a bad headache but didn't feel this bad. I also experience internal tremors in my hands and foot feels wobbly when standing , I was examined by my doctor who said neurological exams is fine. I also feel unblanced when walking and feel like I will pass out my vision I experienced an intense shaking left to right with my eyes and then goes away after a few minutes but then my vision remains blurry , visited the ER did blood tests all normal, and did see a cardiologist all normal 
I am concerned as this pass out feeling , more prominent headache when bending forward , and tremors is making me concerned also this blurry vision 

Have been to the ER multiple times because I'm concerned about a anureysm and brain tumor , considering I had 8 CT scans in the last yr for different issues , but er doctor and family doctor told me no you don't have a brain tumor after examining me..does anyone experience this
