What Causes Left Upper Quadrant Pain Radiating to the Back?
Left upper quadrant pain radiating to the back can be caused by pancreatitis, kidney problems, splenic issues, abdominal aortic aneurysm, and referral of pain from spinal problems.
Kaly specialists regularly aid patients in identifying the underlying source based on a detailed history, physical exam, diagnostic tests, and specialist input.
Pancreatitis
Pancreatitis, or inflammation of the pancreas, is a prime suspect for severe LUQ pain radiating all the way to the back. This condition triggers sharp, stabbing pain that may worsen after eating along with nausea and vomiting.
Gallstones, excessive alcohol use, and high triglycerides often contribute to pancreatitis flares.
Kidney Problems
Kidney infections, kidney stones, pyelonephritis, and other renal issues frequently cause abdominal pain that wraps from the back around to the flank or groin area. This occurs because the kidneys reside in the upper back just under the ribs.
Symptoms pointing to a kidney source include fever, nausea, vomiting, burning urination or blood in the urine. Prompt urinalysis and imaging tests help diagnose kidney-related LUQ and back pain.
Spleen Issues
An enlarged spleen or splenomegaly can potentially provoke LUQ discomfort and pain radiating into the back.
As the spleen swells, it may press on surrounding structures including the diaphragm and nerves, causing referred back pain. An ultrasound helps evaluate spleen enlargement.
Abdominal Aortic Aneurysm
Problems with the abdominal aorta, the major artery supplying the lower half of the body, deserve consideration. An abdominal aortic aneurysm may cause sudden, severe abdominal pain spreading to the back. Imaging tests help assess the abdominal aorta.
Spinal Problems
Lastly, spinal issues affecting the nerves and bones in the thoracic back can cause pain in the LUQ abdominal area. Potential culprits include:
- Compressed or irritated nerve roots
- Osteoarthritis flares
- Muscle sprain or strain
- Fracture

Could Left Upper Quadrant Pain Radiating to the Back and Shoulder Be Heart-Related?
Left upper quadrant pain radiating to the back and shoulder can be heart-related due to referred pain from heart conditions like angina and heart attack.
What is Referred Pain?
Referred pain means pain signals originating from one area, like the heart, are incorrectly perceived by the brain as coming from another area, like the shoulder or LUQ region.
This happens because certain areas share common nerves and nerve pathways. The heart and upper back/abdomen have some overlap in their sensory nerve supply.
- Angina and Heart Attack
Blockages in the heart’s coronary arteries reduce oxygen supply, causing chest pain known as angina. A complete blockage triggers a heart attack.
Lack of oxygen prompts the heart to send pain signals through sensory nerves. But these get misinterpreted as coming from the shoulder, arm, neck, jaw, or upper abdomen rather than the heart.
- Pericarditis
Inflammation around the heart (pericarditis) also irritates local sensory nerves, referring pain to distant areas.
What Causes Upper Left Abdominal Pain Radiating to Back and Shoulder?
Upper left abdominal pain radiating to the back and shoulder can be caused by gastrointestinal issues, cancer tumors, referred pain from the heart or lungs and left kidney problems.
Gastrointestinal Causes
Stomach problems like gastritis, ulcers, and GERD can cause inflammation or irritation that stimulates abdominal pain nerves. These signals sometimes get confused and are perceived as back pain.
Pancreatitis, or inflammation of the pancreas on the left side, can press on or damage local nerves, provoking pain that radiates to the back and shoulder.
Splenic disorders like rupture or infarction cause severe pain that is often referred to the left shoulder through irritation of the phrenic nerve.
Cancer Tumors
Cancers in the upper left quadrant organs like the stomach, pancreas, and colon can compress nerves and surrounding tissues. This releases chemicals that stimulate pain perception in the abdomen and back.
Referred Pain from Other Organs
Heart conditions can sometimes generate referred pain, meaning pain signals are incorrectly perceived as arising from the upper abdomen rather than the heart.
Lung issues like pneumonia can irritate the diaphragm, causing shoulder and upper abdominal pain due to shared nerve supply.
Left Kidney Problems
Disorders like kidney stones, injury, or infection can cause pain that begins in the left flank but wraps around into the upper back.
Could Upper Left Abdominal Pain Radiating to the Back Be Due to Kidney Problems?
Yes, the medical experts at Kaly explain that kidney disorders can potentially cause upper left abdominal pain that wraps around the upper back area. This is because the left kidney sits just underneath the ribs toward the back.
However, many other conditions like digestive, pancreas, spleen, muscle or spine issues can spark similar abdominal and back pain. So how do you know if the kidneys are to blame?
Certain accompanying symptoms and characteristics provide clues that point more specifically to a kidney source, such as:
- Pain accompanied by urinary symptoms like a frequent or urgent need to urinate, burning during urination, or blood in the urine
- Pain accompanied by fever, chills, nausea or vomiting
- Pain localized to the left flank or side under the ribs
However, some kidney problems like cancer may cause only vague, mild pain or none at all in the early stages.
Can Gastritis Cause Left Side Upper Abdominal Pain Radiating to Back?
Gastritis can cause left upper abdominal pain radiating to the back due to inflammation of the stomach lining leading to referred back pain.
What is Gastritis?
Gastritis refers to irritation and swelling of the protective lining of the stomach.
It causes a burning ache or stabbing pain in the upper abdomen, often concentrated in the upper-left quadrant just below the ribs.
Referred Back Pain
With gastritis, the abdominal pain is sometimes perceived as radiating around from the upper front stomach area into the corresponding part of the upper back.
This occurs due to referred pain, when pain signals get confused and are felt in a location distant from the originating spot.
Causes of Gastritis
- H. pylori infection
- Excessive alcohol use
- Frequent NSAID or aspirin use
- Bile reflux
- Autoimmune disorders
- Stress
Complications
- Stomach ulcers
- Bleeding in the stomach
- Rarely, increased cancer risk
What Are the Causes of Upper Abdominal Pain Radiating to Back After Eating?
Upper abdominal pain radiating to the back after eating can be caused by gallbladder disease, pancreatitis, gastritis/ulcers, GERD, or food intolerances.
Gallbladder Issues
Gallstones, inflammation (cholecystitis), or obstruction of the bile ducts often cause:
- Severe upper abdominal pain after eating fatty foods
- Pain may radiate to the back or shoulder
- Other symptoms: nausea, vomiting, fever
Pancreatitis
Inflammation of the pancreas related to:
- Gallstones, alcohol use, high triglycerides
- Causes upper abdominal pain radiating to the back after eating or drinking
- Other symptoms: nausea, vomiting, fever, rapid heartbeat
Gastritis or Ulcers
- Caused by H. pylori infection or frequent NSAID use
- Can cause burning upper abdominal pain radiating to the back, especially on an empty stomach
GERD
- Stomach acid reflux can cause heartburn-like chest pain radiating to the upper back after meals
Food Intolerances
- Allergies or sensitivities to foods like dairy, gluten, alcohol can spark inflammation that worsens pain after eating trigger foods
When Should I Worry About Left Upper Quadrant Pain That Radiates to Back?
Left upper quadrant pain radiating to the back requires prompt medical evaluation, especially if it is severe, persists, or suggests pancreatitis, gastritis/ulcers, splenic disorders, or other serious conditions.
The Kaly medical team advises paying close attention to any left upper quadrant (LUQ) abdominal pain that radiates into your back. Though not always serious, it can signal certain conditions that require prompt evaluation.
Be Concerned About:
Severe, unrelenting LUQ pain spreading to the back, especially if accompanied by:
- Nausea/vomiting
- Fever
- Pain that flares after eating or drinking alcohol
This pattern suggests pancreatitis, or inflammation of the pancreas, which needs rapid diagnosis.
Also, seek evaluation for persistent burning or gnawing LUQ pain radiating to the back. This suggests possible gastritis or peptic ulcer disease related to:
- H. pylori infection
- Excessive NSAID use
- Other causes
Contact your doctor if the pain doesn’t improve after a few days.
Rare Causes
An enlarged spleen (splenomegaly) pressing on nerves can sometimes provoke LUQ and upper back pain.
Seek medical advice for any unexplained abdominal pain lasting more than a few days.
Is Right Upper Quadrant Pain Radiating to Back During Pregnancy Normal?
The obstetricians at Kaly explain that while some back and abdominal pain radiating to other areas is common in pregnancy, certain symptoms warrant medical evaluation.
Mild to moderate back pain radiating into the hips and legs is often caused by posture changes and strain on back muscles as the uterus expands. This is usually normal in the second trimester.
Round ligament pain due to stretching ligaments supporting the uterus can also cause stabbing pain radiating down the thighs when changing position. This is typically harmless.
However, sudden, severe, or persistent abdominal pain radiating to the back can signify serious issues like preeclampsia, appendicitis, ovarian torsion, etc. These require prompt medical diagnosis and treatment.
Symptoms like high blood pressure, fever, nausea, or vomiting accompanying radiating RUQ pain are particularly concerning.
While radiating pain in pregnancy is normal physiologic adaptation, it’s important to contact your obstetric provider for evaluation of any severe, persistent, or worsening pain to check for potential complications.
What Does Left Upper Quadrant Pain Radiating to Back During Pregnancy Imply?
The OB/GYN experts at Kaly explain that mild, temporary LUQ pain is often caused by normal pregnancy-related changes like shifting organs, gas, or constipation. This type of discomfort usually resolves on its own.
However, persistent, severe, or worsening LUQ pain radiating to the back can potentially indicate serious underlying conditions requiring prompt medical evaluation, especially when accompanied by concerning symptoms like:
- Fever
- Vaginal bleeding
- Burning urination
- Severe nausea/vomiting
Potential serious causes requiring urgent diagnosis and treatment include:
- Pancreatitis
- Gallstones
- Preeclampsia
- Placental abruption
- Kidney infections
- Ectopic pregnancy
Urinary tract infections are also relatively common during pregnancy due to physical and hormonal changes.
How to Diagnose Pain Left Upper Quadrant Radiating to Back?
Left upper quadrant pain radiating to the back is diagnosed through medical history, physical exam, imaging tests, and other evaluations to determine the underlying cause and guide appropriate treatment.
The physicians at Kaly explain there is no single definitive test to diagnose the cause of LUQ pain radiating to the back. Doctors use a combination of:
| Diagnostic Approach | Details |
| Medical history | – Details about pain characteristics, timing, triggers, and other symptoms. Helps narrow down the differential diagnosis. |
| Physical exam | – Palpation, checking for organ enlargement/tenderness that may indicate issues like splenomegaly. |
| Blood tests | – Assess for indicators of infection, inflammation, and organ problems. |
| Imaging | – CT scans, MRIs, and ultrasounds visualize abdominal organs and check for abnormalities. |
| Other testing | – Urinalysis for UTI, stool sample for occult blood, endoscopy, exploratory laparoscopy in some cases. |
Getting an accurate diagnosis is critical to guide appropriate treatment and pain management. Doctors emphasize that “pain is not a diagnosis” – the underlying medical cause needs to be determined.
For chronic undiagnosed pain, some patients eventually receive a diagnosis of chronic pain syndrome when no other cause can be found after extensive workup. But ideally, the root issue should be uncovered.
Home Remedies for Left Upper Quadrant Pain Radiating to Back
Home remedies for left upper quadrant pain radiating to the back include acetaminophen, topical heat, ginger, peppermint, chamomile, and other herbs, but medical evaluation is still advised for persistent or worsening pain.
Over-the-Counter Medications
Acetaminophen (Tylenol) can help relieve general abdominal pain by blocking pain signals to the brain. It’s typically the first choice for stomach pain as it is less likely to irritate the stomach compared to other OTC options.
However, high or prolonged use can cause liver damage, so dosing should be followed carefully.
NSAIDs like ibuprofen (Advil, Motrin) and naproxen (Aleve) work by inhibiting the production of inflammatory chemicals. This makes them effective for reducing pain and swelling.
However, they can irritate the stomach lining with frequent use, especially without food, so they should be taken cautiously under medical guidance for persistent pain.
Seeking Medical Care
Home remedies may not be enough for severe, persistent, or worsening pain. Concerning accompanying symptoms like fever, vomiting, or bloody stool warrant prompt medical evaluation.
Doctors can provide stronger prescription pain medications if appropriate and diagnose any underlying condition requiring treatment.
Herbal Remedies
Ginger, peppermint, chamomile, and other herbs may help relieve stomach discomfort through anti-inflammatory, antispasmodic, and analgesic effects. However, research on their efficacy is limited and results can vary individually. They are generally safe to try in moderation.
Heat Therapy
Applying a heating pad or hot water bottle to the upper abdomen may provide relief by relaxing stomach muscles, improving circulation, and having a soothing effect. However, heat should not be applied for too long or on bare skin to avoid burns.
