Talk to Gastroenterologist on Difficulty In Swallowing

I am experiencing difficulty in swallowing food. After eating food it looks like parts of food remain stuck in my throat. It causes pain and discomfort for me. I was caught throat pain and infection two weeks ago. It got disappeared last week, but later, it came again. I visited a homeopathic doctor; he said it is due to extreme acidity and stomach problem. Kindly tell me what its solution.
