4) Sex (some women are allergic to seminal fluid)
5) Hops and barley can cause an allergic reaction
6) Low temperatures
7) Cell phones (due to Nickle content)
8) Pressure (too tight a belt, necktie, bra, etc)
9) Chocolate
10) Exercise (cholinergic urticaria)
11) Vibration (dental drill, lawn-mower, jackhammer, etc)

See your local allergist if you suspect you have this!
