Yes, facial swelling can be part of your Migraines. However, it can also be a side effect of several Migraine medications like depakote and even advil. Next time you go to your doctor, ask him/ her about it to make sure it's not an allergic reactioin to a drug you're taking.
You can go to Drugs.com and enter each drug you are taking and see if facial swelling is listed under the side effects.
