am I having opthalmic migraines? My eye is swollen...

I'm a 29 year old single mom who suffers from migraines. I recently had a migraine that started on a Tuesday and has not stopped since; it is now Saturday. I wouldn't normally be alarmed about the migraines except for the fact that I suddenly developed swelling on my left eye (where the migraine exists) that won't go away. It seems to get bigger as I sleep during the night and gradually goes down during the day but doesn't fully go away. I went to the hospital and the doctor diagnosed me with having opthalmic migraines and perscribed some medicine for it. I would like to know if it is indeed an opthalmic migraine that I'm suffering from and is there something I can do about my swollen left eye.
