Yesterday went to doc for sore throat, cough and fever. given meds including antibiotic. today i have chest pain when cough. what can i do for it. ?

Motrin/mucinex-DM: Possibly pulled a muscle or that the airway is very irritated from coughing/infection..Antibiotics do need time to work--and they only kill the bacteria..Healing is done by the body which takes time. Adding some Motrin and possibly expectorant/cough suppressant such as mucinex-dm may help. Increase fluid, rest, and give your body time to heal..If worsens, call your doc..Good luck.

Pleurisy: Pain on chest excursion (as when inhaling deeply, coughing, etc) is pleurisy. It's typically associated with infectious processes involving the lower respiratory tract. Unless your symptoms resolve quickly on antibiotics, the next step would clearly be a chest x-ray to arrive at a more precise diagnosis and monitor progress.

Possibilities...: This type of chest discomfort, occurring with cough and deep breathing, is usually musculoskeletal in origin. It will improve once the cough resolves. In the meantime, local heat to the area and Motrin are ways to get symptomatic relief. If it persists, see your doctor.
