Chronic cough : A chronic cough with nasal symptoms and not feeling sick sounds like an allergic problem. Allergies are a chronic disease that often is annoying but not severe. When severe, allergy patients can have a worse average quality of life than cancer patients. A chronic cough for two months could be a viral bronchitis resolving slowly, or asthma, or a subacute sinus infection. Time to see an allergist.

Allergies?: Sounds like you are allergic to something in your bedroom or shower. Check for mold in the shower.
