Pain is the body’s most effective alarm system. While muscular and skeletal pain are easier to pinpoint, organ pain can be far more mysterious, elusive, and, at times, alarming. It doesn’t always feel like a sharp jab or an obvious cramp—sometimes it manifests subtly, as a dull ache, tightness, or even radiating pressure.
Dr. Jordan Sudberg, a nationally recognized pain management specialist, has helped countless patients navigate the confusing landscape of internal pain. In this post, Dr. Sudberg unpacks what organ pain really is, how to recognize it, what causes it, and when to seek medical attention.
What Is Organ Pain?
Organ pain refers to discomfort that arises from internal organs—structures like the stomach, kidneys, liver, lungs, pancreas, or heart. Unlike musculoskeletal pain, which is often localized and triggered by movement or pressure, organ pain is typically visceral. This means it stems from the internal organs within the chest, abdomen, or pelvis.
“Organ pain is often harder to diagnose because the pain signals are not as precise,” explains Dr. Jordan Sudberg. “The nerves that connect our organs to the brain aren’t as well defined as those in the skin or joints, so the brain may interpret internal discomfort as diffuse or referred pain.”
In other words, pain in your left shoulder might actually be coming from your spleen, or discomfort in your back might be a signal from your kidneys.
Why Is Organ Pain So Difficult to Identify?
The body’s visceral pain system is designed to sense distention, inflammation, and ischemia (a lack of blood flow), but not necessarily sharp injuries. That’s why many people don’t immediately associate their discomfort with a specific organ.
Dr. Sudberg emphasizes that internal pain often comes with accompanying symptoms—such as nausea, fever, shortness of breath, or abnormal lab tests—which can provide vital clues. “The pattern of symptoms, not just the location of the pain, helps us identify its true origin,” he says.
Common Types of Organ Pain (and What They Might Mean)
Let’s break down some of the most common sources of organ pain and how they may present:
1. Liver Pain
- Location: Right upper abdomen, possibly radiating to the right shoulder
- Sensation: Dull, aching pain
- Possible Causes: Hepatitis, fatty liver disease, liver cancer, or congestion due to heart failure
Dr. Sudberg advises, “If you’re experiencing pain in the upper right quadrant along with fatigue or yellowing of the eyes, it’s important to get liver function tests immediately.”
2. Kidney Pain
- Location: Flank area or lower back, just under the ribs
- Sensation: Sharp, cramping, or dull aching
- Possible Causes: Kidney stones, infections, cysts, or hydronephrosis
“Kidney pain can mimic back pain,” says Dr. Sudberg, “but the difference lies in associated symptoms like painful urination, fever, or blood in the urine.”
3. Heart Pain (Angina or Myocardial Infarction)
- Location: Center or left side of chest, may radiate to arm, jaw, or back
- Sensation: Pressure, squeezing, or a heavy weight on the chest
- Possible Causes: Heart attack, coronary artery disease, pericarditis
“This is a medical emergency,” warns Dr. Sudberg. “If you’re experiencing chest pain with shortness of breath, dizziness, or sweating, call 911.”
4. Pancreas Pain
- Location: Upper middle abdomen, often radiating to the back
- Sensation: Severe, unrelenting pain
- Possible Causes: Pancreatitis, pancreatic cancer
“Pancreatic pain often intensifies after eating and can come with nausea or vomiting,” says Dr. Sudberg. “It’s one of the more serious causes of abdominal pain.”
5. Stomach Pain
- Location: Upper or mid-abdomen
- Sensation: Burning, gnawing, or cramping
- Possible Causes: Gastritis, ulcers, acid reflux
Stomach-related pain is very common but can still signal serious problems if accompanied by weight loss, black stools, or vomiting blood.
6. Gallbladder Pain
- Location: Right upper abdomen, especially after fatty meals
- Sensation: Sharp or cramping
- Possible Causes: Gallstones, inflammation (cholecystitis)
“Gallbladder pain can start suddenly and often occurs at night or after a heavy meal,” Dr. Sudberg notes. “Ultrasound is the go-to test for diagnosis.”
7. Lung Pain
- Location: Chest, often worsened by breathing
- Sensation: Sharp or stabbing
- Possible Causes: Pleurisy, pneumonia, pulmonary embolism
Lung pain should never be ignored, especially if it comes with coughing, fever, or difficulty breathing.
Referred Pain: The Hidden Complexity
One of the biggest challenges in diagnosing organ pain is referred pain. This happens when pain is felt in a different location than its source. For example:
- Gallbladder pain may be felt in the right shoulder
- Diaphragm irritation can cause neck pain
- A heart attack may cause jaw or arm pain
Dr. Jordan Sudberg explains, “Referred pain occurs because of the way our nerves are wired. Organs share nerve pathways with other parts of the body, making it difficult for the brain to pinpoint the exact source.”
When Should You See a Specialist?
While not all organ pain signals an emergency, certain signs should prompt an immediate visit to a healthcare provider or pain specialist:
- Persistent or worsening pain
- Pain accompanied by fever, nausea, or vomiting
- Sudden, sharp pain without obvious cause
- Pain that interferes with daily function or sleep
- Blood in urine, stool, or vomit
Dr. Sudberg notes, “Pain is never ‘just in your head.’ If something feels wrong, trust your instincts and seek an evaluation. The earlier we identify the cause, the better the outcome.”
Diagnosing and Treating Organ Pain
The process of diagnosing organ pain often includes:
- Medical history and physical exam
- Blood tests and urinalysis
- Imaging (ultrasound, CT, or MRI)
- Endoscopy or colonoscopy if gastrointestinal causes are suspected
As a pain management expert, Dr. Jordan Sudberg works collaboratively with gastroenterologists, cardiologists, urologists, and radiologists to determine the source and develop a treatment plan. Options may include:
- Lifestyle changes (diet, exercise, stress management)
- Medications (anti-inflammatory, antispasmodic, antibiotics, etc.)
- Interventional procedures such as nerve blocks
- Surgery in severe cases
Final Thoughts: Listen to Your Body
Organ pain isn’t something to guess about—it’s a signal that something deeper is happening within. Whether it’s a minor issue or a major concern, early recognition and treatment are key.
Dr. Jordan Sudberg emphasizes that “pain is a diagnostic tool, not just a symptom to suppress. Our job is to listen to what the body is telling us, identify the underlying cause, and use every tool available—from conservative care to advanced diagnostics—to restore health.”
If you or a loved one is experiencing unexplained internal discomfort, don’t wait. Reach out to a pain management professional like Dr. Jordan Sudberg for a comprehensive evaluation and expert care.
