Gosh, if you ave an ongoing headache that never stops - that sounds similar to what happened to me. My second neurologist suspected an increase in intracranial pressure and ordered a spinal tap. The headache I had was literally excruciating and got progressively worse over a six month time until she ordered the spinal tap. (It was on our second visit.)

I had to live laying down in the dark with black out curtains over the windows for months on end. The headache hurt my eyes too - it's one of the symptoms of increased intracranial pressure, but the symptoms can very between patients.

The severe pain I was in was relieved within five minutes after the spinal tap.

You might want to bring it up with your neuro next time you see her.
