Hydration : Make sure you are taking in enough fluids throughout the day. Start drinking more water. Coffee and soda are not appropriate fluids because the caffeine is a diuretic. Your chest pains may be just from trying to bring up sticky phlegm. Excessive coughing will tire the chest muscles. Hydrate and take some Mucinex (guaifenesin) to thin the secretions.
