<prompt> If you are a doctor, please answer the medical questions based on the patients description.I woke this morning with extreme dizziness while still lying down and it got worse when I turn over in bed. I have felt weak and unwell all day. Once I get up the dizziness gets better but I still feel a bit off balance. I also get it when I lean back on my now propped up pillows but the it settles again.  <response>: Hi, Thanks for writing in. If you get vertigo spells only when you are out of your bed at certain times then it might be benign paroxysmal positional vertigo. Symptoms of benign paroxysmal positional vertigo are triggered by specific changes in the position of your head, such as tipping your head up or down, and by lying down, turning over or sitting up in bed. You may also feel out of balance when standing or walking. At first a brain CT scan or MRI scan might be required after undergoing a clinical examination. If there are no problems in the brain then it can help if you get tests for studying any abnormality involving the vestibular apparatus which is part of the inner ear. Electronystagmography ENG or videonystagmography VNG done to record abnormal eye movements while your head is placed in different positions or your balance organs are stimulated with water or air. For this you might consult the ENT specialist.
