I keep having pains in my esophagus. At times it is in different spots. It sometimes starts at the top of my stomach and moves up my chest. At times it is kind of in the middle of my chest and moves up to my throat. There is a pain right in the center of my chest and then it feels like there is a charlie horse in my throat. It happens all day and all night. It wakes me up several times a night. I have never felt anything like this before.
