Suggest Treatment For Severe Migraine

For the past 24hours I ve had a metallic/iron smell in my nose. Prior to this I ve been having horrible migraines, 3weeks now, that aren t alleviated with any type of over the counter meds(only try them once a day) throughout the day seeing black spots, can t seem to mentally focus. On the really bad days it hurts my head to ay down, whatever area is on the pillow has unbearable pressure. Only meds I take some birth controll, Tryc line. I work in a hospital and am exposed to everything
