Hi doctor! From time to time I feel like undigested food is stuck in the esophagus. Because I'm in the epidemic season, I only go to the store to buy medicine, but it helps but when I eat food, it is still difficult to digest (jackfruit and fried foods). So the doctor asked me to feel like food is not digested, is it dangerous to get stuck in the esophagus? I hope the doctor can help me. I would like to thank you.
