I think I am getting sick

I feel like I am coming down with something I have alot of nasal congestion and drainage (clear), no fever, no shortness of breath, weight is steady, and no releasing of fluid / matter from either end, constant cough, headache.... self diagnosis allergies or some sort of a summer cold.... it is time to pop some new pills after a nasal was.
