Notice dizziness and feelings of imbalance. Determine if your dizziness is related to moving your head. Look for nausea and vomiting. Pay attention to numbness, weakness, or slurred speech. Figure out if your symptoms are recurrent.
Primary symptoms of vertigo include dizziness and a sense of imbalance. If you feel as though you are spinning or your environment is spinning, this suggests vertigo. Feeling as though you are going to fall over or being unable to balance yourself also suggest vertigo. These symptoms could be caused by inflammation of the vestibular cranial nerve, so it's important to visit your doctor and get a definitive diagnosis. Changing the position of your head can often increase dizziness or vertigo symptoms. Everyday activities like lying down, turning over in bed, bending down, and tilting your head can cause light-headedness or nausea. The most common cause of this type of recurrent positional dizziness is Benign Paroxysmal Positional Vertigo (BPPV). The feeling of unsteadiness can make you nauseated. In turn, that can cause you to vomit. If you notice these symptoms in addition to the dizziness, you likely have vertigo. If parts of your body feel numb or weak, or if you have trouble walking along with symptoms of vertigo, you could be suffering from a more serious condition. Also, note if your speech is slurred, which could indicate a stroke or transient ischemic attack. If you experience these symptoms often, rather than once in a long while, you may be suffering from vertigo. If you have recurrent episodes of dizziness, nausea, vomiting, imbalance, and hearing loss, you could be suffering from Meniere's disease. Other symptoms of this disease include ringing in your ears or a sensation of fullness in your ears. See your doctor if you are experiencing any of these issues.
