My wife has MS; diagnosed in 2006 - for the past 2 years she s been suffering from sudden choking when taking her first bite of a meal or a sip of water. Our EMT son suggested MS Hug; however, she experiences severe compression between her sternum and throat, and almost always vomits contents from her throat, not her stomach. Once had to call 911 due to her inability to breath. Suggestions, recommendations, or any pre-pre diagnosis thoughts?
