My name is Susan, age 67 with a 46 year history of Myasthenia Gravis. Up until January of 2013, whenever I had a crisis situation, I was evaluated and given a new med and had to wait sometimes 6-12 months to get results. Prior to Jan 13, I began to have difficutly swallowing but the dynamics of this situation were unlike those I had when the MG symptoms reappeared. Neurology sent me to Speech and Language therapy. Video of my swallowing found the problem to be a faulty valve or muscle of the esophagus. Then, I was sent to gastro for endoscopy and ph testing of the acid in my stomach. All were negative. I am also seeing a neurodentist who believes the swallowing problem is related to a misaligned jaw and I have been wearing an appliance for the past four months to keep my jaws lined up properly. I must remove the appliance to eat and chew, but I am still not swallowing with less difficulty with the appliance in or out.What are your thoughts? Blood work is done on a regular basis and there is nothing there to cause great concern.I would greatly appreciate any time you spend looking into this problem as no one I have seen the almost two years has been able to figure out what to do.Thank you in advance.Susan Opp
