What causes pressure in head and dizziness?
Patient: Hey my head feels weird, like it has a little pressure and slight dizziness at times. My heart feels like if it beating a lil fast and not too long ago while I was in bed I felt like I couldn t move, or open my mouth to talk as if I had a very mini stroke it seizure. Please help. Doctor: Hi,Thanks for writing in.In your case the possibility of a seizure or evolving stroke needs to be evaluated.Dizziness can be due to many reasons and can happen due to decreased blood flow from heart to brain. When it happens, the blood flowing through the vessels from heart to brain might have a reduced flow. These are by the carotid and vertebral arteries on either sides. This can also happen due to momentary reduction in blood flow through the carotid arteries due to the pressure of a cervical rib or degenerative changes in the cervical spine, when you look up, down or turn your head.A clinical examination by the neurologist is essential to know the investigations to be further done for you. While bony cervical ribs or degenerative changes in cervical spine can be seen on X ray,  a brain scan and other investigations to study the flow of blood to the brain might also be required as a part of evaluation.Dizziness can also occur due to problems in the inner ear and balance mechanism of the body.
