If you've not experienced headaches before, most likely it's due to other stresses. When I hear allergic reactions, I imagine it to be a REACTION (quick, abrupt, etc.)...so I think if you are sensitive to glues, pieces, etc., the sensitivity would have manifested earlier and not wait until now.

The best way to know is see how you feel AFTER finals :lol:

Good luck on finals!
