Post nasal drip: It seems you have post nasal drip and other symptoms that can be related to a cold or nasal allergies. You do not mention how long you have had this condition. If it comes and goes, you need to tell your doctor and perhaps see an allergist. If it is mor erecent, use a saline nasal spray to alleviate your nasal symptoms, it will improve your post nasal drip.
