Hello, My Name Is Anna. About 8 To 10 Mos

Hello, my name is anna. About 8 to 10 mos ago i started getting constantly dizzy in the top of my head. About 4 mos ago i started having uncontrolable movements with my head to the side like a so ft jerk. My dr thought it might be my lisinopril for high blood pressure so he changed my med to metropolol er 25mg and i take norvasc 10 mg also. I recently lost my health insurance so i was not able to go back to him. It has been 2 mos since i saw my dr. My head feels very heavy pretty often. It seems to get worse when i'm tired. My movement in my head is worse and more often now. I specifically notice it when i lay on my pillow and when i sit on a sofa and lean my head on it. When i'm at work and i get tired, i am forgetting the most common things. There is not much pain accept a little bit of a burning sensation on the left side of my head if u r looking at me. The dizziness is constant now. When i get tired my dizziness is getting worse. Can think of anything this might be? Thank you so much for your time on this. ANNA HOWARD
