dizzyozzie,

Welcome to NeuroTalk.

It sounds like you are on the right track with the vestibular therapist and neck. The question is. What is being done to help your neck heal properly? Are you doing range of motion exercises to maximize range of motion or a more gentle therapy to help your neck get stable? Gentle is usually better. How do you take care of your neck when you sleep?

What is the symptom the doctor is targeting with the Zoloft? It is not usually used for PCS unless one is struggling with anxiety or depression.

Amitriptyline is commonly prescribed in low doses for insomnia and headaches.

Have you tried anti-inflammatory pain relievers for your headaches? Ibuprofen or aspirin (enteric coated) can be worthwhile. Tylenol/acetaminophen can help with pain, especially when combined with aspirin but Tylenol alone does not provide much anti-inflammatory effect. Have you done any icing of your upper neck?
