I have had a migraine for 4 weeks with pain near my temples with varying intensities. i have nausea, reduced short term memory, and insomnia ?

Seen a doc yet?: Get examined. Find out if this is truly migraine, as opposed to e.g. sinus, tumor, other vascular, muscle tension, etc. Get appropriately diagnosed and treated. Migraine should not last for 4 weeks.

Pattern: You now have Chronic Daily Migraines, a pattern which needs to be disrupted. Your symptoms are consistent and do not necessarily suggest an unknown syndrome. Would urge you to connect with a headache specialist and address this pattern.
