Dizziness can be caused by a sudden drop in blood pressure or being dehydrated. In your case, it seems that you can pinpoint a time when you started to feel dizzy. This will be helpful as you look for a diagnosis.

Dizziness usually gets better by itself or is easily treated. However, it can be a symptom of other disorders. Did you start any medications recently? Medicines may cause dizziness. Have you have problems with your ears? Ear problems can also make you feel dizzy. Motion sickness can also make you dizzy. There are many other causes.

I suggest that you see your doctor to find the cause for this symptom. Be prepared to describe your dizzines and when it began. The more information you can provide, the better informed your doctor will be.
