question: Hello doctor, A few months before, I felt burn and pain in the chest area when I swallow anything like my own saliva. It lasted more than a week and again I felt normal. Again yesterday, I started to feel this pain and I started to think about that and felt stress. Tonight, when I swallow anything I feel this chest pain and burn. And when I do not swallow also I feel pain in the chest area. Is it serious and should I worry about that? When I searched on the internet it says big diseases like esophageal cancer. The symptoms say difficulty in swallowing, coughing and things and now I feel like I am feeling all those symptoms. Please help.
