Thanks for staying Online. I am posting my answer.
Well, having dizziness which come after tilting head or bending, is related with a condition Benign paroxysmal positional vertigo called as BPPV.
Such episodes can come, and then go and then again re-occur. It occurs when the semicircular canals in ear, become sensitive to changes in head position, and may occur when you lay on bed.
Also with this ,change in positions such symptoms appear. And BPPV usually lasts a minute or two. It can be mild, or it can be bad enough.
Your doctor will do test- Dix-Hallpike test.
Doctor can treat this condition with series of movement called as canalith repositioning procedure.This can be done by doctor.
Also Thyroid function test, Blood sugar test should be done.
For the time, you can take Tab. Dimenhydrinate(Dramamine) for dizziness.It is OTC drug.
I would recommend you to consult ENT doctor for clinical evaluation and get it managed.
God bless you and take care.
