Does anyone have experience with a chiropractic neurologist?

My injury was a little over two years ago. My fatigue and other symptoms, such as sensitivity to screens, nausea, headaches, have been getting worse so I sought out some alternative care. We had an initial assessment, almost 2 hours of questions and in-office testing, such as eye movement, walking certain ways, etc. Very pricey.

The next day I was unable to leave the couch - this lasted for 4 days, and is slowly tapering off. I didn't make the connection before this, but the Dr said it was likely caused by the in-office tests.

His treatment plan is 3 short sessions a week, so it won't trigger the symptoms so dramatically. It's more money than we have, but we could probably manage it for a short time. I would also have to drive on the freeway for 30 min each way, and that doesn't always feel good to me.

Does anyone know if a chiropractic neurologist can be helpful?

By the way, he also suspects my adrenal glands could be playing a part, and we're waiting on that test.

I have faith in this particular doctor, but I can see that the whole process is drawn out as much as possible, so they can get the maximum amount of money from the patients.
