Hi, Thank you for your question. I would recommend that you consult a neurologist to find out the exact cause of your vertigo. He/She would like to suggest few exercises that may be of help in your condition. These exercises like epley may help in improving vestibular nerve (Nerve involves in balance) function so the condition. In addition, I would suggest getting a neurologist opinion here as well in order to get complete neurological assessment and further approach. Hope this helps.
First of all, depends why you are having the dizziness or vertigo; what is causing it. Dizziness and vertigo are NOT the same thing.
Other than a prescription from a doc, then motion sickness pills at the drugstore, like the kind with Meclazine in it. It'll make you a little drowsy and out-of-it, so keep that in mind as to when you take it.
