I have a really bad cough and running nose and head aces and its really hard to breath. what can i do?

Symptomatic treatmen: The cause and more importantly the treatment for your symptoms depends on the history of how long you have had your symptoms. If it is less than a week you probably have a viral infection and the nasal stuffiness would be helped by oral or intranasal decongestants. The cough can be bronchospasm and an inhaled bronchodilator may be helpful. For the headache i would use Acetaminophen or ibuprofen.
