What Can Cause Itchy Red Swollen Blotches Under Eyes?

I am a 45 year old male and have no allergies. 24 hours ago I woke up with red, mildly swollen blotches about 1cm in diameter under each eye. I have never had this condition previously. This morning (approx. 24 hrs following initial indication) I woke up to find the continuation, and somewhat progressed red blotches under both eyes. They are both slightly more swollen, and are beginning to itch.1) What are the likely causes and identification of this condition? 2) How can I treat it? Thank you in advance for any assistance you might be able to provide. Victor Dith US DOD contractor Baghdad, Iraq
