whirlign feeling in head

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. Anyone have any ideas?

The eye exam was a great start and it would have been better with an eye MD rather than an optometrist, but at least that doc can can get a fairly good look at the optic nerve which is the clue.

I would think with wooshes, the ears and/or sinuses could be a factor. Sinus infections can just sit there. Ear stuff like vestibular disturbances can effect the hearing. Have you seen an ENT anytime recently?

They can also rule tumors in and out via general exam with reflexes etc. So I would look at the ears next.
