Experiencing abdominal pain and back pain at the same time can be unsettling – especially when it’s hard to pinpoint where the discomfort is actually coming from. The two symptoms might seem unrelated, but abdominal pain with back pain occurring together is actually a recognized pattern across a number of conditions, ranging from mild and manageable to situations that require urgent medical attention.
At Davies Pharmacy, our team provides pharmacy services and health guidance to help North Shore residents understand their symptoms and make informed decisions about their care.
Why Abdominal and Back Pain Can Occur Together
The abdomen and back share a complex web of nerves, muscles, and organs. Many of the organs housed in the abdominal cavity – including the kidneys, pancreas, uterus, and aorta – sit close to or against the back, which means inflammation, infection, or dysfunction in these organs can produce pain that radiates in both directions simultaneously.
In other cases, a musculoskeletal issue in the lower back creates referred pain that feels like it originates in the abdomen, or vice versa. Understanding this relationship helps explain why the two symptom sites so frequently appear together.
Common Causes of Abdominal Pain with Back Pain
The possible causes span a wide range. Some are straightforward and resolve on their own. Others require prompt medical assessment. Here are the most common conditions associated with this symptom combination.
Kidney Stones
Kidney stones are one of the most frequent causes of simultaneous abdominal and back pain. As a stone moves through the urinary tract, it can cause intense, cramping pain that typically starts in the flank – the area between the ribs and hip on one side – and radiates around to the lower abdomen and groin.
The pain from kidney stones is often described as coming in waves and can be severe. It may be accompanied by nausea, vomiting, blood in the urine, or a burning sensation when urinating. If you suspect a kidney stone, medical assessment is important – smaller stones may pass on their own, but larger ones may require intervention.
Kidney Infection (Pyelonephritis)
A urinary tract infection that travels to the kidney causes pain in the lower back or flank alongside abdominal discomfort. Unlike a standard UTI, a kidney infection typically also produces fever, chills, and general unwellness. This is a condition that requires antibiotic treatment and should not be left unaddressed.
Pancreatitis
The pancreas sits behind the stomach, close to the spine, which is why inflammation of this organ – pancreatitis – frequently causes pain in both the upper abdomen and the back. The back pain is often described as a deep, boring sensation that is somewhat relieved by leaning forward.
Pancreatitis can be acute or chronic. Acute pancreatitis is typically associated with gallstones or heavy alcohol use and can range from mild to life-threatening. It requires medical evaluation.
Gallstones and Gallbladder Issues
Gallstones or gallbladder inflammation can cause pain in the upper right abdomen that radiates to the right shoulder blade or upper back. Pain often comes on after eating, particularly after fatty meals, and may be accompanied by nausea or vomiting.
Aortic Aneurysm
An abdominal aortic aneurysm – a bulging in the main artery that runs through the abdomen – can cause a deep, persistent pain in the abdomen and lower back. This is a serious condition, and a rapidly enlarging or ruptured aneurysm is a medical emergency. It is more common in older adults, particularly men with a history of smoking or cardiovascular disease.
If abdominal and back pain is severe, sudden, and accompanied by dizziness or a pulsing sensation in the abdomen, call 911 immediately.
Endometriosis and Gynecological Conditions
In women, endometriosis – a condition where tissue similar to the uterine lining grows outside the uterus – is a significant cause of pelvic pain that radiates to the lower back. The pain is often cyclical, worsening around menstruation, though it can be present throughout the month in more advanced cases.
Other gynecological conditions including ovarian cysts, fibroids, and pelvic inflammatory disease can also present with combined abdominal and back pain.
Musculoskeletal Causes
Not every case of abdominal pain with back pain points to an internal organ. Muscle strain, poor posture, and spinal conditions like a herniated disc can create referred pain that mimics abdominal discomfort. In these cases, the pain tends to worsen with certain movements and improve with rest.
Core muscle strain – from heavy lifting, sudden movements, or prolonged poor posture – can create tension across both the abdominal wall and the lower back simultaneously.
Irritable Bowel Syndrome (IBS)
IBS is a common functional gastrointestinal condition that frequently causes abdominal cramping accompanied by lower back pain or discomfort. The back pain in IBS is thought to result from referred pain through shared nerve pathways. It typically accompanies episodes of bloating, gas, diarrhea, or constipation.
Urinary Tract Infections
Even an uncomplicated lower UTI can sometimes cause discomfort that extends beyond the bladder, producing a dull ache in the lower abdomen and back. If you have UTI symptoms – burning urination, urgency, and frequency – alongside back pain, speak with a pharmacist or doctor promptly, as treatment with antibiotics is typically needed.
Symptoms That Require Emergency Care
While many causes of abdominal pain with back pain are not immediately dangerous, some symptom combinations require urgent or emergency medical attention. Call 911 or go to the nearest emergency department if you experience:
- Sudden, severe abdominal or back pain that is unlike anything you’ve felt before
- Pain accompanied by a pulsing sensation in the abdomen
- Fainting, dizziness, or a rapid drop in blood pressure
- High fever alongside severe abdominal and back pain
- Pain following a traumatic injury
- Chest pain accompanying abdominal and back discomfort
- Signs of shock – pale, cold, clammy skin, rapid breathing, or confusion
According to the Mayo Clinic, severe or persistent abdominal pain always warrants medical evaluation, particularly when it occurs alongside other concerning symptoms.
When to See a Doctor
Outside of emergency situations, it’s still worth seeking a medical appointment if:
- Abdominal pain with back pain has lasted more than a few days without improvement
- Pain is recurring or becoming more frequent
- You have a fever, unexplained weight loss, or fatigue alongside pain
- Pain is interfering with sleep, work, or daily activities
- You’re unsure what is causing your symptoms
A doctor can perform a physical examination and order appropriate investigations – blood work, urine analysis, ultrasound, or imaging – to identify the underlying cause and recommend treatment.
Managing Milder Symptoms at Home
For cases where the cause is known and not medically urgent – such as IBS-related discomfort, mild muscle strain, or a confirmed UTI being treated with antibiotics – there are practical steps to manage pain and support recovery at home.
Over-the-counter pain relief – NSAIDs like ibuprofen can help with inflammation-related pain and are appropriate for many musculoskeletal and mild gastrointestinal causes. Acetaminophen is an alternative for those who cannot take NSAIDs. Always follow dosage instructions and speak with a pharmacist if you’re unsure which option is right for you.
Heat therapy – A heating pad applied to the lower back or abdomen can ease muscle tension and provide comfort during cramping or spasms.
Hydration – Adequate fluid intake is particularly important for kidney-related pain and UTIs, as it supports urinary tract function and helps flush the system.
Rest and gentle movement – For musculoskeletal causes, a balance of rest and light movement – avoiding prolonged sitting or heavy lifting – is generally recommended.

Frequently Asked Questions
Can abdominal pain and back pain occur at the same time without a serious cause?
Yes, absolutely. Muscle strain, IBS, gas and bloating, and menstrual cramps are all common causes of simultaneous abdominal and back pain that are not medically serious. That said, if the pain is severe, sudden, or accompanied by other symptoms like fever, vomiting, or urinary changes, a medical assessment is warranted.
What does kidney pain feel like compared to back pain?
Kidney pain typically presents as a deep, aching sensation in the flank – the area between the lower ribs and the hip on one or both sides. It may radiate to the lower abdomen or groin. Unlike muscle-related back pain, kidney pain is not usually worsened by movement or position changes, and is often accompanied by urinary symptoms.
Should I go to the emergency room for abdominal and back pain?
It depends on the severity and accompanying symptoms. Sudden, severe pain – especially with fever, vomiting, dizziness, or a pulsing abdominal sensation – requires emergency care. Pain that is manageable, has a known cause, or is improving can typically wait for a doctor’s appointment or a pharmacist consultation.
Can stress cause both abdominal and back pain?
Yes. Stress activates the body’s fight-or-flight response, which can tighten the muscles of the back and abdomen and exacerbate functional gastrointestinal conditions like IBS. Chronic stress is a recognized contributor to both back pain and digestive discomfort.
Is it normal for a UTI to cause back pain?
A lower UTI can occasionally cause mild lower back discomfort, but significant back or flank pain alongside UTI symptoms may indicate that the infection has spread to the kidneys. This requires prompt medical attention and antibiotic treatment beyond what is typically used for a standard UTI.
