Thanks to everyone for the comments. You are wonderful friends. I'm blessed.
Jim, my condition has a few names. The two main ones are Pseudotumor Cerebri and Intracranial Hypertension. It's more common in women but men can have it too.
There aren't really any definitive tests except by process of elimination, but having a spinal tap after everything else is negative will solidify a diagnosis, as the spinal pressure would be elevated but the fluid must be clear.
Keep me posted. I hope this isn't what you have, but at the same time, it's nice to know what is going on. I didn't know for years.
