You are experiencing "DYSPHAGIA" or difficulty swallowing, which can be caused by a variety of things. How old are you and how long have you been noticing this? Generally, symptoms lasting longer than a few weeks should be reported to your doctor, who may wish to send you for tests, specifically an upper GI series of c-rays or a modified barium swallow, which is just a fancy name for an x-ray that closely analyzes your swallowing of different fooRAB (and video tapes the results for analysis).
