I have been experiencing migraine for a few yrs off and on. Over the last two yrs occurrences have increased, began having auras, last Sunday had 2 auras in one day. Recently very sleepy all the time, sometimes blurry vision, minor memory impairment (I make lists a lot to remind me to do things especially at work). Sometimes have trouble finding right words or speak incorrectly but not slurred. Frequent nausea w HA. Occasional vomiting. HA more often in am. On nadalol BID, chlordiazepoxide/amitriptyline at HS. Prn imitrex tabs and IM c rare relief. Have not had MRI in 10 yrs. Frustrated! Does this warrant another MRI? Could it be s/s of something else?
