Sore throat, tight chest, cough?

Tight chest/ throat : Most cough with sore throat for few days are viral. Tight chest could mean asthma or bronchospasm or simply chest pain because of coughing , so i would suggest you to see a dr. If you are asthmatic you need to use your bronchodilators. The decision to use or not antibiotics is up the treating physician when there is a question for bacterial infections.

Probably URI: These are classic and common symptoms for many viral illnesses, along with muscle soreness (myalgias), headaches and fever. However, more info is needed to be sure a more serious infection or other process imitating URI is present. And if someone has asthma or COPD (emphysema), a tight chest can indicate less airflow.

Bronchitis?: It is possible these symptoms are due to acute bronchitis caused by either a bacterial or viral infection. See your doctor for diagnosis and treatment.
