ineffective esophageal motility disorder and electric shock sensation

I've been dealing with swallowing issues for over a year and a half now. They began after a course of beta blockers. After two manometry tests, 3 barium swallows and two endoscopies, i've been diagnosed with ineffective esophageal motility disorder and a sliding hiatal hernia. I also have pretty bad acid reflux. I have trouble eating anything that isn't liquid now. The only solids I can eat are saltine crackers, graham crackers and shortbread cookies, basically anything that's a meltable solid. As part of this issue, i get what feels like random electric shock sensations over my chest. They are quick and usually are a result of how I'm sitting or something I've eaten that's more solid. My heart has been ruled out, so these sensations are coming from the esophagus, i assume. Has anyone experienced this sensation as part of esophageal motility issues or hiatal hernia? Also, just doing another random check-in to see if anyone has ever been successfully treated for esophageal motility disorders. I sure do miss the luxury of solid food. Curious as to what doctors at mayo are good to see about esophageal motility disorders that are not achalasia. Thanks!
