I have acid reflux. my throat really hurts and now my right ear hurts. it feels like it's a lump in my throat. what does that mean?

Globus or LERD?: 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-esophaeal reflux without heartburn. Sometimes, the actual swallowing mechanism may be impaired due to "spasms" or dysmotility. Gastroenterologist or ENT specialist is a good starting point for evaluation of this complex phenomenon.
