One of the most common health conditions in the United States is acid reflux. It is when stomach acids bubble up into your esophagus and throat. Burning sensation in your chest or throat is the main symptom.

Joseph Murray, MD, a GI doctor and researcher at Mayo Clinic, says: "I also see reflux being blamed for symptoms that have nothing to do with it."

These are the unexpected signs you might be suffering from acid reflux:

Fowl or bitter taste

According to Mayo Clinic research appearing in the American Journal of Medicine, the stomach juices force their way up into your esophagus, leaving a sour or bitter taste in the back of your throat.

Recurring pneumonia

As Murray says, when the stomach acids escape your belly, they do not just irritate your throat, but they also make their way into your lungs. He also explains that in case this happens, you can end up with "a nasty case of pneumonia."

Unexplained chest pain

A lot of people mistake heartburn from a heart attack. But, it is not unusual to see someone in the ER with serious chest pain, thinking it is a heart attack, when it is actually reflux. But, unfortunately, the opposite can happen with tragic results. According to Murray: "Someone is having a heart attack, but they don't go to the ER because they figure it's indigestion. When in doubt, go to the emergency room."
