A.A.
The same thing happened to me a week ago and I thought the same thing about the allergies and it lasted for about 5 days. I couldn't wear make-up or anything and this past Monday I woke up with a sore throat, itchy (not watery) eyes and serious cough. I stayed at home for 2 days i feel better now but I still have a mild cough.
Anyway, I did not go to the doctor I just loaded up with allergy and sinus medication.
Good luck.
