Hi – I have severe esophageal spasm from a disease called Eosinophillic Esophagitis. This is presumed to be caused by some type of allergy, although all of my allergy tests came back negative. EoE is a fairly newly discovered illness and was previously presumed to be a childhood issue. But more and more adults are beginning to be diagnosed via endoscopy. I have to have endoscopic dilations every 2-4 months to assist me in the dysphagia. In answer to the question about what esophageal spasms feel like, the best description I have heard from others and that I can relate to is that of a heart attack. Now, being that I am only 46 years old and reasonably healthy, I don’t know what a heart attack feels like. But, I work in the healthcare industry and have been admitted with chest pain more than once. All of the physicians I have spoken to say that I (and others with EoE) describe my pain exactly how a heart attack sufferer would. It’s no fun and I’m sorry for anyone else who suffers from this. Take care everyone.
