Sorry to inform you, but you might have pseuotumor cerebri. This won't kill you but can cause lots of problems. The biggest is loss of your eyesight, so you need to see a neuro-ophthalmologist. Also request a lumbar puncture to measure the pressure of spinal fluid in your spinal column. As you probably can tell, I'm speaking from experience. I had all the test you described and the LP was the tell-all. But run to the neuro-opht today, don't wait. You can loose some eyesight. Best wishes
