question: Hi doctor, I am 32 years old. I have GERD since a few years as the doctor told me after a diagnosis where he took the camera inside the food pipe. Anyway, I used to smoke then I quit but recently I smoked a bit when I was in holiday, after coming back from holidays I am getting a lump like feeling under my Adam's apple, just where the neck and the chest meet when I swallow food or saliva. It is very disturbing. I went to the doctor and he told it is maybe because of inflammation of the food pipe and gave me to do an ultrasound but everything went well. Nothing was found. But the feeling of something stuck is making me worried. Should I be concerned?
