For the past 2 days, I have a painful feeling in my chest, in my esphagus I guess. It is that feeling when you swallow food and it goes down really slow and it's painful, like it hasn't gone down all the way. It's not debiltating pain or anything, just a tightness and sort of uncomfortable but won't really go away and I was wondering if I should be concerned and call my doctor. Or is this something that can occasionally happen? How long do I wait before I call my doctor if it continues? I have no problems at all in the past so not sure what it is. Any advise is appreciated. Thanks.
