Try using the term "facial edema" when you see the doctor. It means swelling of the head in the area of the face, but using this term should motivate your doctor to do some actual thinking about what's going on with you.
Because this type of swelling can indicate serious issues, such as massive allergic reactions (to food, or medicine, especially), and it should not be brushed aside.
If you can tolerate diphenhydramine (brand name is Benadryl) oral, it may help with this while you're waiting to see the doc. And if it *does* help, definitely tell the doc about that too, because it's an antihistamine, and that just adds weight to the *TAKE IT SERIOUSLY, PLEASE!* issue.
Good luck...
