Globus sensation?: Do you experience the feeling of a ball or lump in the back of your throat that you have to swallow past? If so, this is "globus." alternatively, you may have laryngo-esophageal reflux without heartburn. Sometimes, the actual swallowing mechanism may be impaired due to "spasms" or dysmotility. A gastroenterologist or ear-nose-throat specialist is a good starting point for evaluation.
