Brief Answer:
BPPV likely

Detailed Answer:
Thank you for asking

I read your question and I understand your concern. Dizziness with motion of the head and posture change is likely BPPV (benign paroxysmal positional vertigo) and is commonest cause of all. If you had some recent flu or any ear pain that could also lead to such complaints.

All you need is wait and see policy because it self resolves over a couple of weeks. You may take some antivert for the symptomatic relief or any other vestibulosuppressant medication. Canalith repositioning and Cawthorne exercises along with many other vestibular rehab exercises can be considered as treatment modality.

Just seek a neurologist or an otorhinilaryngologist and let them take care of the symptoms.

I hope it helps. Take good care of yourself and don't forget to close the discussion please.

Regards XXXXXXX
