Really worried about this one. So like for the last 3 days, I feel like a very mild chest pain a little bit to the left side everytime I eat. I notice it everytime food passes down that area. What I really find odd is if this is reflux or anything related to the esophagus, then the pain would be in the middle where the esophagus was. It's very mild pain, kinda like burning type, but it is there. Of course, my mind is thinking that maybe I've got a tumor in that area and food comes in contact with it whenever it passes down my esophagus. I'm 35 and I know esophageal cancer is quite rare for that age but I still can't stop worrying. Just need a bit of reassurance maybe.
