Left-side pain under the ribs is a common complaint among women, yet it often causes confusion and concern due to the range of potential causes. Understanding what might be behind this discomfort and knowing when to seek medical attention can make a significant difference in health outcomes. Dr. Erin N. Marcus, MD, MPH, professor of clinical medicine at the Miller School of Medicine at the University of Miami, provides insights into some of the primary causes of this pain, including heart disease, pulmonary embolus, pneumonia, and muscle strain. Alongside these, pain in the lower left abdomen and the key questions doctors ask during evaluation also shed light on the diagnostic process. This article offers a thorough explanation of these causes and practical guidance for women experiencing left-side rib pain.
4 Causes of Left-Side Pain Under the Ribs
Left-side pain beneath the rib cage can arise from a variety of conditions. Dr. Marcus identifies four particularly significant causes that warrant attention due to their potential severity and frequency.
Heart Disease: A Silent but Serious Threat
Heart disease remains a leading cause of pain under the left ribs in women, primarily because the heart lies in the chest’s left upper quadrant. Angina or even a heart attack can present with pressure or stabbing pain in this area, sometimes radiating to the back or arm. Women’s symptoms may differ from men’s, often being subtler, such as mild discomfort, indigestion-like sensations, or fatigue accompanying the pain. According to the American Heart Association, heart disease is the top cause of death for women, underscoring why early evaluation is critical.
Pulmonary Embolus: When a Clot Causes Chest Pain
A pulmonary embolus (PE) occurs when a blood clot blocks an artery in the lungs, causing sharp, sudden pain under the ribs on the left or right side, depending on which lung is affected. This condition may also come with shortness of breath, rapid heartbeat, or coughing blood. PE demands urgent medical attention due to its life-threatening nature. Dr. Marcus emphasizes that any abrupt onset of severe rib pain coupled with breathing difficulties warrants immediate emergency care.
Pneumonia and Other Lung Issues: Infection and Inflammation
Infections such as pneumonia can cause localized left-rib pain, especially when the lower lobe of the left lung is involved. This pain often worsens with deep breaths or coughing. Other pulmonary problems like pleurisy—the inflammation of the lung lining—can produce similar sharp pains. Women with fever, chills, and persistent cough in addition to rib pain should consult their healthcare provider promptly, as untreated pneumonia can escalate quickly. “If the patient has a fever or chills or is coughing, we might consider pneumonia,” Dr. Macus says. Other concerning diagnoses could be a tumor in the lungs or elsewhere in the chest, particularly in a smoker or someone who has been exposed to toxic fumes.
Muscle Strain: The Most Common and Often Overlooked Cause
Muscle strain due to physical exertion, heavy lifting, or even coughing can lead to pain beneath the left ribs. This pain tends to be localized and worsens with movement or touch. Unlike the other causes, muscle strain is less serious but can still be distressing. According to Dr. Marcus, a careful history of recent activities is essential to differentiate muscle pain from more serious conditions.
9 Causes of Pain in the Lower Left Side of the Abdomen
Pain on the left side, just below the ribs or in the abdomen, could indicate a different set of medical issues. Dr. Marcus outlines these common causes:
- Diverticulitis (inflammation of small colon pouches)
- Kidney stones
- Urinary tract infections
- Constipation
- Ovarian cysts or torsion
- Endometriosis
- Gastrointestinal issues such as irritable bowel syndrome (IBS)
- Hernias
- Ectopic pregnancy
Each condition has a unique presentation and severity, stressing the importance of accurate diagnosis.
What a Doctor Might Ask About Pain in the Left Side of Your Abdomen
When you present with left-side abdominal or rib pain, your physician typically investigates through a detailed history, aiming to pinpoint causes based on your symptoms. Some common questions include:
- When did the pain start, and how has it changed?
- Is the pain constant or intermittent?
- Does anything make the pain better or worse?
- Are there associated symptoms such as fever, nausea, shortness of breath, or urinary changes?
- Do you have any relevant medical history like heart disease or lung conditions?
This inquiry guides further diagnostic tests, from blood work to imaging studies. For example, sudden left-side chest pain may trigger an EKG and chest X-ray, while lower abdominal pain might lead to ultrasound or CT scans.
The Bottom Line on Left-Side Pain in Women
Left-side pain under the ribs or in the lower abdomen in women is not a symptom to ignore. Although many cases are benign, some point to serious conditions requiring urgent care. Heart disease, pulmonary embolus, pneumonia, and muscle strain are among the pivotal causes Dr. Marcus highlights for chest-level pain. Meanwhile, the nine causes affecting the lower abdomen add complexity to diagnosis but are commonly encountered in clinical practice.
Women experiencing sudden, severe, or persistent pain in these areas should seek prompt evaluation. Early diagnosis can save lives, improve treatment success, and reduce complications. Healthcare providers rely on a mixture of history-taking, physical exams, and diagnostic testing to unravel the cause behind the discomfort.
Understanding the spectrum of possibilities—and the signs that demand immediate attention—empowers women to advocate for their health with confidence and clarity.
