When the pain starts my whole body aches and i feel weak. also the coughing as well.

Viral: This most likely is a viral upper respiratory tract infection and the chest distress can be from tracheobronchial inflammation and harsh coughing. This type of infection tends to resolve with resting, drinking adequate fluids and to suppress a dry,hacking cough ,taking a cough suppressant syrup like robitussinDM. See a physician if symptoms don't gradually improve or if they worsen.
