I would suggest you take a course of Tab. Amoxyclav for 10-14 days. Chest pain is quite common when we constantly cough.  So once your Infection is controlled , your cough will reduce , so will your chest pain . Until then you can take simple analgesic like Tab. Paracetamol if you have too much pain.You can also get a Chest Xray done to ensure there s nothing else causing your chest pain .  Hope my reply helps.  Do drop in your valuable feedback. </s>
