Dave, I'm glad you at least know what is going on. Please make sure that they look at your other conditions, in case other things are going on. Too bad you can't go to Mayo in AZ.

Ask them a lot of questions! Make sure that you research the treatment options before making any decision. They can all have a long-term impact on your health, and you have to consider your other conditions as well.

Have they determined a cause of the leukocytosis?

A neuro will usually run a CT chest scan as well, looking for signs of thymic hyperplasia or a thymic tumor. Some patients can have either of those things.

If you need anything else, just ask. I hope the appointment goes well.
