Chronic hoarseness, throat clearing, and cough as well as a feeling of a lump in the throat or difficulty swallowing may be signs that you have LPR. Some people do have heartburn, too. Some people have hoarseness that comes and goes, others have a problem with too much mucus or phlegm. If you have any of these symptoms, and especially if you smoke, you should ask your doctor about LPR. The specialist who most often treats people with LPR is the Otolaryngologist (Ear, Nose, and Throat Physician).
