When meds won't work

Apparently I have a mild to moderate sulfa allergy to sumatriptan. It should have relieved my migraine headaches, but it didn't. Such an expensive drug put to waste in my system. I have some kind of hives or probably angioedema around my left eye and left forehead.

I think I would like to reconsider another diagnosis aside from migraine. This case is far too long to continue for 7 days or more, and there's no relief to be found with acetaminophen, ibuprofen, naproxen, diclofenac, and sumatriptan. I read somewhere that this could be cluster headache, but I could be wrong.

More importantly however, I would like this pain to stop. I have three exams this week, and I don't know if I'll survive them.
