I feel for you, I've had a swollen forehead like this a couple of times...I'm living in Asia. We (my boyfriend is a doctor) kind of figured out it happens when I get too much sun on my head and overheat. I took antihistamines and an ibuprofen for the swelling.
As for the alternative anti-histamines I find that ceterizine isn't as effective as loratadine (I have a lot of allergies too). ...
