Welcome @jsh468, I'm sorry you haven't had any answers yet from the doctors you've seen following the surgery. I think I would try and plan your conversation with the neurologist so that you can explain when the symptoms first started and how they have progressed possibly due to significant external stressors. There is a great website with some tools to help you plan your conversation with the neurologist (or any healthcare appointment) that you might find helpful.

When is your appointment with a neurologist? Can you let us know what you find out?
