My mother in law is feeling woozy and seeing white spots. i initially thought blood pressure but her bp is 126/80. what else could it be ?

Vague Symptoms: Pt's age? meds she is taking? physical condition she is in? heart disease? diabetes? smoker? alcohol ? If the unsteadiness continues /worsens you need to go to the Emergency room during the episode. A battery of basic tests +/_ a CT can help determine the cause of her symptoms. The Ddx could be med AE, dehydration, low bld sugar, the start of a stroke. to mention a few possibilities.
