Hi I have been experiencing indigestion after every meal for about a month now. It s not painful, I just feel the food going coming back up slowly, say as far as my chest and then going back down. It s lasts for about 20 mins after I eat and sometimes I belch to get it to go away, after which, I get relief. It also happens when I drink, and is actually worse if I have drink with my meal. Should mention that for the last 5 or 6 years I have always coughed after a meal for a few seconds to feel clear .
