One particular digestive disorder that causes many people a lot of distress and misery is acid reflux back pain. Now, you may be thinking – isn’t acid reflux got something to do with heartburn? You would be absolutely right, however acid reflux disease can cause secondary symptoms and back pain is one of them.
To help you understand how back pain can result from acid reflux, it is better that I briefly explain to you, how acid reflux or gastroesophageal reflux disease (GERD) is caused in the first place.
The main cause can be linked to a round shaped muscle called the lower esophagus sphincter. This muscle is located at the bottom end of your esophagus, just before the entrance to your stomach. If you’re not sure what the esophagus is, it is simply the long tube, in which your food and drink travel down, on the way to your stomach.
Now, the job of the lower esophageal sphincter is to act like a one stop valve. This means it should only open one way. This is to enable your food and drink to enter into your stomach and, then it should shut. Sometimes, this valve-like muscle becomes too relaxed or weakens and does not close fully.
By doing so, the stomach acid can flow back up (reflux) to your esophagus and its corrosive effect can cause symptoms such as chest pain, heartburn and a sore throat.
How Acid Reflux Causes Back Pain
Not everyone who suffers from acid reflux, will experience back pain however, it can happen. It is important to point out, that back pain caused by acid reflux, is not the result of muscular strain or injury.
The pain is actually a reflection of the esophageal region becoming inflamed, as a result of the stomach acid traveling upwards. The area affected is the upper chest region, which is directly opposite to your upper back or the area between your shoulder blades.
