I would look to change doctor's if my doctor said "Wow! I have no idea what that might be", and didn't immediately follow up with "Let me check into that and I'll get back to you in a couple of days"
For a doctor to say "I have no idea what is wrong with you, see ya, have a nice day" is absolutely a disaster waiting to happen.
If your ticker is fine, I agree with whoever recommended the neurologist. Hopefully the compressed spine is the more likely cause and not something like a tumor in the brain. As you said it has happened occasionaly for a year or more, I think the brain tumor is not likely, but you never know.
