I have a heartburn kind of feeling every three days once in a week. Its like two days the acid reflux is gone and after 5 days it will come back. This has been has been happening since last month. My esophagus is also getting a burning sensation also, I have a difficulty in swallowing food. Its like now I have a sour taste in my mouth. I had to force myself to eat today bcoz I had a loss of appetite and I do not feel hungry at all. I do not have an appetite but I feel full even with a little meal of two idli and half a cup of rice. Is this normal?
