How do you tell the difference between sinus infections and allergies?
I've had an on-and-off headache/head congestion and been feeling nauseated since yesterday evening. Today, my throat is sore. Normally, my allergy symptoms are itchy, watery eyes, runny nose & sneezing--not anything else. So I'm leaning toward a sinus infection. But the last time I had a sinus infection, my headaches/head congestion were MUCH worse.
Either way, my immune system is evil
