Hello dear, Thanks for being on healthcaremagic.com. If you would have presented to me as an outpatient,I would have made the following clinical explanation- What you have described is close to the classical description of migraine with visual aura. Visual aura(left eye blurring in your case) followed by severe headache(along with retro-orbital pain) associated with nausea and improved after rest-is the typical sequence of events in migraine with aura. You are having this headache episodically again confirms it of being migraine.Migraine headache can be followed by a tendency towards sleepiness and it improves with sleep.Your family doctor is probably right in saying that you have a migraine.Please discuss with your physician to put you on preventive and abortive therapy for migraine and I hope you will be fine.I hope it helps.
