For the last week I have been getting sharp pains on the left side of my head on and off. Sometimes it is very painful when it happens. I had a very bad migraine earlier this week that normally would stop after taking prescribed sumatriptan. This day it would not stop despite my effforts. At this time I notice the sharp pain. Although my migraine is now gone. I am still getting the sharp pain on and off on the left side of my head. Should I have a CT done? I did see my MD the day after the bad migraine.
