Have you felt a piercing pain under your left rib when you take a breath or move just the slightest bit sometimes? While it is common to experience such pain, sometimes it can be an indication of an injury or trauma in the stomach or any vital organ on the left side of your body. In this article, we take a deeper look at the different factors behind the pain under your left rib.

Causes And Symptoms Of Pain Under The Left Rib Cage

Sharp pain under the left rib cage could be due to a variety of reasons. Several organs are located in this region of your body – like your heart, spleen, lung, colon, kidney, pancreas, and stomach. Hence, the causes of left side pain below the ribs can be many.

While most of these causes can be treated right at home, some of them could be life-threatening and may need immediate medical diagnosis, followed by appropriate treatment.

The life-threatening causes of the pain under your left rib cage include:

1. Heart Attack

The symptoms of a heart attack (other than dull pain under the left rib cage and back)include the following:

    • A sudden feeling of dizziness
    • Fatigue
    • Nausea
    • Heartburn
    • Indigestion
    • Cold sweat
    • Shortness of breath
    • Tightness, aching, or pressure in your chest that spreads to your jaw, back, or neck (1)

2. Angina

This is also a heart-related condition that can cause pain on the left side of the body under the ribs. Angina refers to severe pain in the chest that may spread to the shoulders, arms, and neck. This left side rib pain occurs when the blood traveling to your heart lacks oxygen. Its symptoms are similar to that of a heart attack – like dizziness, shortness of breath, fatigue, sweating, etc. (2).

A survey involving 1612 adults with coronary artery disease (CAD) established that angina is a common issue in patients with CAD in the US. 21.2% of the surveyed patients reported experiencing angina at least once a month. Out of them, 12.5% of people experienced it daily or weekly, and 8.7% of them monthly.

3. Pericarditis

This condition is caused due to the swelling of the membrane (pericardium) surrounding your heart. There are four types of pericarditis:

  • Acute Pericarditis: Its symptoms last for less than 3 weeks.
  • Incessant Pericarditis: Its symptoms are continuous and may last for 4-6 weeks.
  • Recurrent Pericarditis: Its symptoms keep recurring every 4-6 weeks.
  • Chronic Pericarditis: The symptoms usually last longer than 3 months.

The symptoms of pericarditis are:

  • Sharp pain and tenderness in the middle or left of your chest
  • Fatigue
  • Cough
  • Unusual swelling of your abdomen/leg
  • Heart palpitationsi  A sensation that the heart is missing heartbeats, pounding and racing due to stress and variation in breathing.
  • Shortness of breath
  • A slight fever (3)

4. Cancer

Cancer-related rib pain may vary in intensity, but is generally in the mild to severe range. Painful rib metastasis (the spread of cancer cells) is a common symptom in non-small cell lung cancer (4). When cancer cells metastasize to the rib bone, they may cause rib pain. In rare cases, cancer may originate in the ribs and cause discomfort and pain in the rib cage. Some cancer treatments like radiation therapy may also cause pain and inflammation in the ribs. You may also experience rib pain when a tumor presses against nerves in the rib area. Hence, it is important to consult your healthcare professional if you are experiencing persistent rib pain to get a proper diagnosis and treatment plan.

5. Gastrointestinal Disorders

Gastrointestinal disorders include conditions, such as irritable bowel syndrome, hemorrhoidsi  Swollen, enlarged, and inflamed veins in the anus and lower rectum that cause pain, bleeding, and discomfort. , constipation, perianal abscesses, etc. The digestion-related causes of pain under the left rib cage after eating include:

  • Trapped gas in the digestive tract
  • Constipation
  • Heartburn
  • Gastroesophageal reflux disease (GERDi  A chronic digestive disorder in which stomach acid repeatedly flows back and irritates the food pipe lining. )
  • Irritable bowel syndrome (IBS)
  • Inflammatory bowel disease (IBD)

Pain caused due to digestive issues like gastritis, diverticulitis, and stomach ulcers may possibly cause pain at or referred to the left upper quadrant. Dr. Taryn Silverstein, a board-certified gastroenterologist and a member of the Gastroenterology Associates of Florida (GAF), says, “Diverticulitis more commonly presents with pain in the left lower quadrant, and gastritis/gastric ulcers more typically cause pain in the epigastrium (upper, center abdomen below the sternum), which may radiate to the back.”

Avoid spicy or hot foods and alcoholic beverages. They may lead to IBD and gastrointestinal issues and trigger pain under the rib cage.

6. Issues With Other Organs

As we have already mentioned, there are other organs located in the upper left abdominal region of your body, and issues with them can also trigger a sharp pain under your left rib cage.

Such issues include:

  • Kidney stones – They are hard calcium deposits that form in the kidneys and later move towards the bladder, causing extreme pain while passing urine. Kidney stones may be caused by not drinking enough water or consuming too much salt or sugar.
  • Pancreatitis – Inflammation of the pancreas.
  • An enlarged spleen – The spleen is located in the upper portion of the left rib cage and is normally about the size of your fist. An enlarged spleen is caused due to liver infections, cirrhosisi  Chronic liver damage in which normal liver function is impaired due to the formation of scars. , etc.

7. Infections

Certain infections may also be responsible for the sudden ache in the left part of your chest like:

  • Pneumonia, which causes sharp chest pain while coughing.
  • Pleurisy – an infection that causes the membrane surrounding your lungs to become inflamed.
  • A collapsed lung
  • Broken ribs
  • Endocarditis, which causes an infection in the inner lining of your heart.
  • Appendicitis – A condition that causes inflammation of your appendix.
  • Costochondritis – A condition that causes inflammation of the cartilage that connects a rib to the breastbone.

If costochondritis is causing pain and soreness under your left rib, avoid exercises or sports that may strain the chest muscles. Maintaining proper posture may also reduce pain.

In addition, conditions related to the female reproductive system, such as ovarian cysts, endometriosis, or pelvic inflammatory disease (PID) may cause left side pain under the ribs in females.

If you have developed any of the above health conditions, you are at a higher risk of developing pain under your left rib cage. Hence, it can be said that all these conditions act as risk factors behind pain in the left rib cage.

It is best to consult a doctor immediately if you experience any of the other symptoms of the life-threatening conditions listed above. Your doctor or cardiologist is most likely to carry out the following diagnostic analysis to rule out other conditions associated with the pain under your left rib cage.

Once the cause of the pain is determined, your physician will prescribe treatments accordingly.
