Some other causes of dizziness are dehydration, infections,TIA,inner ear diseases,endocrine disorders like thyroid, adrenal glands, and pituitary gland disorders,anxiety
and panic attacks,blood pressure medications,
pain relievers
and some antibiotics.Cervical spondolysis,vertebrobasilar insufficiency and carotid sinus syndrome can also cause dizziness.
I sincerely advise you to consult a physician/ENT surgeon and get these possibilities ruled out.
