Need Help! Severe Headache, Neurologic Symptoms

I am posting this again because I really need help.  I've had a severe, persistent, incessant headache for four months.  The symptoms are bizarre, and came on very rapidly.  It started as a cap of pain at the top of my head, sometimes squeezing, sometimes pressure, then burning and tingling.  It then spread to the rest of my head, sometimes on one side, sometimes the other.  Sometimes back at the top, sometimes at the back, or behind the ears.  In other words, the pain travels.  My ears hurt off and on, and I have intermittent tingling in the right side of my face and in my legs, arms, and chest.  In addition, I have tremors in both hands, and episodes in which the skin over my whole body feels like it is on fire.  I also have the sensation of pressure/heaviness/hardness in my chest and esophagous.  And there is some problem with my right eye, diagnosed as anisocoria, but no apparent reason for the pupil's uneven dilation, and the optometrist says the optic nerve and retina are healthy.  The eye also hurts more often than not.  And I have general fatigue, and often feel weak and shaky.  I have had a CT, MRI, and CTA of my brain, and an MRI of my spine, all normal.  I have also had a lot of bloodwork done, and again, no sign of infection, inflammation, auto-immune disorder, etc.  The doctors are baffled.  I've been referred to a neurologist, but there's a waiting list (County Hospital).  Has anyone ever experienced anything like this?  What could it be?
