I have colds for years. i have it when i was in highschool but now i'm a fourth year college and i still have this cold. ?

Probably not a cold: A cold is the common name for an upper respiratory tract infection, which are caused by a variety of viruses, mostly rhinoviruses and adenoviruses, but actually many viruses (including the one that causes polio) can present initially with upper respiratory symptoms. True colds come and go and don't stay with people. If they are constant, it is more likely allergic in nature. An allergist may help.
