Can GERD Cause Back Pain?
Clifton Physical Therapy
If you have burning in your chest after a meal and an ache between your shoulder blades a little later, it is reasonable to wonder whether the two are connected. GERD is usually thought of as a digestive problem, but symptoms from the esophagus can sometimes be felt outside the chest, including in the back.
The important part is not to assume that every episode of upper or mid-back pain is caused by acid reflux. Back pain has many possible causes, from muscle strain and poor posture to spinal problems and other digestive conditions. But when back discomfort repeatedly appears along with heartburn, regurgitation, or symptoms that worsen after eating or lying down, GERD may be part of the picture.
What Is GERD?
Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach contents repeatedly flow back into the esophagus, the tube that carries food from your mouth to your stomach.
The lower esophageal sphincter normally acts as a valve, opening when you swallow and closing afterward. When this barrier does not work properly, stomach contents can move upward into the esophagus and irritate its lining.
The most familiar GERD symptoms are heartburn and regurgitation. Heartburn usually feels like a burning sensation behind the breastbone, while regurgitation can feel like food or sour liquid coming back up into the chest or throat. GERD can also be associated with difficulty swallowing, chest discomfort, chronic cough, or throat symptoms.
GERD is common. The American College of Gastroenterology estimates that up to 20% of people in the United States have GERD. However, occasional heartburn is not automatically GERD. Frequent symptoms, generally occurring at least twice a week, or evidence of reflux-related damage can indicate the disease.
Can GERD Cause Back Pain?
It can be associated with back pain, but back pain is not one of the classic symptoms used to diagnose GERD.
One possible explanation is referred pain. The esophagus and other structures in the chest share connections with sensory nerves that enter the spinal cord. Because the brain does not always identify the exact source of visceral pain, irritation in the esophagus can sometimes be perceived in another area.
Research supports the existence of this type of referred pain. In a study of patients with non-erosive reflux disease, researchers found that patients had larger areas of referred pain after esophageal stimulation than healthy controls. The study also found increased sensitivity to heat stimulation in the esophagus.
There is also newer evidence connecting esophageal symptoms with back pain. A 2024 study compared 150 patients being evaluated for esophageal symptoms with 150 patients undergoing screening colonoscopy. Back pain was reported by 74% of the esophageal-symptom group compared with 55% of the control group. After participants were separated according to whether they had esophageal symptoms, those with symptoms were 3.3 times more likely to report back pain. Thoracolumbar pain was the most common location.
That finding is interesting, but it needs to be interpreted carefully. The study showed an association between esophageal symptoms and back pain. It did not prove that GERD directly caused the participants' back pain.
What Does GERD-Related Back Pain Feel Like?
There is no single type of back pain that proves GERD is responsible. When reflux-related discomfort is felt in the back, it may be described as a burning, aching, pressure-like, or uncomfortable sensation, often around the upper or middle back.
Some people notice the discomfort around or between the shoulder blades. Others may feel discomfort lower around the thoracic or thoracolumbar region. The location alone, however, cannot distinguish GERD from a muscle, joint, rib, or spinal problem.
The pattern is often more informative.
For example, suppose you normally feel fine while moving around during the day, but after a large meal you develop heartburn followed by discomfort between your shoulder blades. If the same pattern occurs repeatedly, the digestive symptoms deserve attention along with the back pain.
On the other hand, pain that clearly increases when you bend, lift, twist, reach, or sit in one position for a long time may point more toward a musculoskeletal problem.
There can also be an overlap. Someone with reflux may change the way they sit, stand, breathe, or move because their chest or upper abdomen feels uncomfortable. Over time, these changes can add muscle tension to the upper back. In that situation, the back pain may not come directly from stomach acid. Instead, reflux symptoms and the resulting movement or posture changes may contribute to the discomfort.
How GERD and Back Pain May Be Connected
There are a few ways reflux symptoms and back discomfort can overlap. One is referred pain, where irritation in the esophagus is perceived somewhere other than the original source. Another is the way people change their posture or breathing when they are dealing with chest or upper abdominal discomfort.
Sleep can add another layer. Nighttime reflux may interrupt sleep or make it uncomfortable to lie flat. Poor sleep does not cause a spinal injury, but it can make existing pain feel more difficult to tolerate.
There is also an important point about the anatomy. The diaphragm surrounds the opening where the esophagus passes into the abdomen, and part of the diaphragm attaches to the lumbar spine. A 2024 study involving 300 people found a significant association between esophageal symptoms and back pain, with the thoracolumbar region being the most common location. The researchers proposed that changes involving the esophageal hiatus and surrounding structures could be one possible explanation.
That does not mean a tight back muscle causes GERD or that GERD automatically produces back pain. The relationship can be more complicated, with digestive and musculoskeletal factors occurring together.
GERD Back Pain vs. Other Causes of Back Pain
The timing and accompanying symptoms can provide useful clues, although they cannot replace a medical evaluation.
| Pattern | May Suggest GERD-Related Discomfort | May Suggest a Musculoskeletal Problem |
|---|---|---|
| Timing | Appears with heartburn, regurgitation, or after meals | Changes with movement or physical activity |
| Location | Often upper or middle back, sometimes around the shoulder blades | Can occur anywhere along the back |
| Position | May worsen when lying down, particularly after eating | May worsen with bending, lifting, sitting, or certain movements |
| Other symptoms | Sour taste, burning chest, belching, difficulty swallowing | Stiffness, muscle tenderness, restricted movement |
| Response | May improve when reflux is controlled | May improve with movement, rest, exercise, or physical therapy |
These patterns are not absolute. A person can have GERD and mechanical back pain at the same time. In fact, that is often more useful to consider than trying to force every symptom into one diagnosis.
If your pain is clearly affected by reaching, lifting, twisting, prolonged sitting, or certain exercises, a musculoskeletal assessment may be appropriate even if you also have reflux.
What Can You Do About GERD-Related Back Pain?
The first step is to address the reflux itself. Physical therapy cannot stop stomach contents from flowing into the esophagus, so persistent GERD symptoms should be discussed with a physician or gastroenterologist.
Some lifestyle changes have good clinical support. Current American College of Gastroenterology guidance recommends weight loss for people who are overweight or obese and suggests avoiding meals within 2 to 3 hours of bedtime. For nighttime symptoms, elevating the head of the bed may also help. The guidelines also support identifying and avoiding foods that consistently trigger an individual's symptoms rather than assuming every person needs the same restrictive diet. Practical steps include:
Eat smaller meals if large meals trigger your symptoms.
Give yourself at least 2 to 3 hours between your evening meal and bedtime.
Stay upright after eating rather than lying down immediately.
Identify your personal trigger foods instead of eliminating large groups of foods unnecessarily.
If you are overweight, discuss weight management with your healthcare provider.
Follow prescribed GERD treatment as directed.
Keep moving, particularly if prolonged sitting or inactivity also contributes to your back discomfort.
Medication may also be appropriate. Antacids can provide short-term relief, while H2 blockers and proton pump inhibitors are used for longer-lasting control in appropriate patients. The right medication and duration depend on the person's symptoms and medical history.
How Physical Therapy Can Help
Physical therapy does not treat GERD itself. Its role is to address the back pain, stiffness, muscle tension, posture, and movement problems that may occur alongside reflux.
A physical therapist may look at how your upper back, shoulders, neck, ribs, and thoracic spine move. If you have developed a habit of rounding your shoulders or guarding your chest because of discomfort, treatment may include gentle mobility work and exercises to restore more comfortable movement. Treatment may include:
Posture and movement training
Thoracic mobility exercises
Strengthening
Breathing exercises
Ergonomic advice
The goal is not to label every case of back pain as "GERD back pain." A good assessment should also consider whether there is an independent problem involving the spine, muscles, joints, or nerves.
When Should You See a Doctor?
Back pain accompanied by occasional heartburn does not necessarily mean you have GERD. But persistent or frequent reflux symptoms deserve medical attention, particularly if over-the-counter medication is needed repeatedly. Seek prompt medical evaluation if you have:
Difficulty or pain when swallowing
Food feeling stuck in your chest
Unexplained weight loss
Vomiting blood
Black or tarry stools
Persistent vomiting
Significant or worsening chest pain
Shortness of breath or other concerning symptoms
If your upper or mid-back pain keeps coming back with heartburn or reflux, it may be worth having the musculoskeletal side of the problem evaluated. Contact Clifton Physical Therapy at (973) 241-1338 to schedule an evaluation and learn how physical therapy may help relieve your back discomfort.
