Blocked nose: Your symptoms suggest an upper respiratory tract infection. Irrigate your nasal passages with warm salt water and use a decongestant nasal spray to clear the blockage. Worsening cough, fever,copious discolored sputum, wheezing, severe inspiratory chest pain or shortness of breath would require prompt examination by a physician or visit to the hospital emergency room.
