Laura76,

Welcome to NeuroTalk.

Your husband's experience is not uncommon. He has likely suffered a subtle neck or upper spine injury. He might benefit from some gentle chiropractic care or a physical therapist with expert skills with subtle neck and spine injuries. With his level of symptoms, I am surprised he has not had an MRI of his neck.

You may look into Atlas Orthogonal or NUCCA chiropractic.

He also need to practice disciplined neck posture to help his neck heal, especially when he is resting or sleeping.

What meds has he been put on ?
