You need some type of decongestant (but not an antihistamine). Sudafed is one of the better OTC's out there. Be sure you look at the ingredients list, though. Some types of sudafed only has 30mg of pseudoephedrine (the active ingredient), but others have 60mg. If you're really that congested, I recommend the higher strength. That should help with the ear/nasal/sinus congestion. For the coughing, I recommend hot tea with a lot of honey.
