In March I started getting this off and and on head wooshes, or head rushes. Usually concentrated to one area of my head at a time, but the sensation happens in different spots. It lasted about 3 weeks, I went to my PCP and had a comprehensive eye exam with an optometrist, and both said everything looked okay. It went away for about 3 weeks and has not come back.
I am not having any other symptoms, no nausea, no headaches or anything else. But my mind is focused on the possibility of a brain tumor, and it is kind of freaking me out. It happens sometimes when my eyes are closed as well.
