Your spleen sits just under your left ribs, behind your stomach. Most people never feel it. So when a dull ache or a sharp pain shows up in that spot, the first question is whether it is the spleen at all, and the second is whether it is serious.
Spleen pain is felt in the upper left part of the abdomen, under the lower left ribs, and it can spread to the left shoulder. Most of the time it means the spleen is enlarged because of an infection, a liver problem or a blood condition. Rarely, it means the spleen has torn, which is an emergency.
This guide explains exactly where spleen pain is felt, how to tell it apart from other left-side pain, the most common causes, and the warning signs that mean you should not wait. If you want the basics first, start with what the spleen does and where it is.
Key takeaways
- Spleen pain sits in the upper left abdomen under the ribs. It can spread to the left shoulder and often gets worse when you breathe in deeply.
- The usual cause is an enlarged spleen, and the usual reasons for that are infections such as mononucleosis, liver disease, and blood disorders or blood cancers.
- An enlarged spleen often causes no pain at all. Feeling full after a few bites of food is sometimes the only clue.
- Sudden severe pain under the left ribs with dizziness, a racing heart or left shoulder pain, especially after a blow to the body, can mean a ruptured spleen. Go to the emergency department.
- Treatment targets the cause. The spleen usually shrinks back once the infection or condition behind it is treated.
Spleen pain location: where it is felt
The spleen is tucked under the left side of the rib cage, roughly level with the lowest ribs, next to the stomach. A healthy adult spleen is about 12 centimeters long and weighs around 70 grams, according to the Cleveland Clinic. At that size it is protected by the ribs and a doctor cannot normally feel it.
If you want the full picture of the organ itself, our guide to spleen function and location covers it. For the pain, the pattern is recognizable:
- Location: the upper left abdomen, just below or behind the lower left ribs.
- Spread: it can travel to the left shoulder or the upper back. This happens because the diaphragm, which sits on top of the spleen, shares a nerve with the shoulder.
- Character: usually a dull ache or a feeling of pressure and fullness rather than a sharp stab. It often feels worse when you breathe in deeply or press on the area.
- Company: feeling full after eating only a small amount, because a swollen spleen presses on the stomach.
Pain that is lower down, near the hip, or on the right side is not the spleen. Pain that comes in waves with bloating is more likely to be the bowel, and pain that rises into the chest after meals is more likely to be the stomach or acid reflux.
What spleen pain feels like compared with other left-side pain
| Where and how it feels | More likely cause |
|---|---|
| Dull ache under the left ribs, worse on deep breaths, full after small meals | Enlarged spleen |
| Sudden severe pain under the left ribs plus left shoulder pain, dizziness, fast heartbeat, often after an injury | Ruptured spleen, an emergency |
| Burning behind the breastbone or upper middle abdomen, worse after meals or lying down | Stomach acid, gastritis or reflux |
| Cramping pain across the abdomen with bloating, gas or a change in bowel habit | Bowel, such as constipation or irritable bowel |
| Sharp pain in the left flank or back spreading to the groin, sometimes with blood in urine | Kidney stone or kidney infection |
| Pain at the lower left ribs that is worse when you twist or press on one rib | Pulled muscle or rib injury |
These overlap, and no table replaces an examination. Use it to understand what your doctor will be thinking about, not to diagnose yourself.
What causes spleen pain
An enlarged spleen (splenomegaly)
Almost all spleen pain comes from a spleen that has grown bigger than normal. The Mayo Clinic stresses that an enlarged spleen is not a disease in itself. It is a sign that something else is going on, and it is often discovered during a routine examination before it causes any symptoms.
The spleen enlarges because it is working harder than usual: filtering out more damaged blood cells, fighting an infection, or holding blood that cannot flow freely through the liver. The conditions that most often cause it fall into a few groups.
Infections
- Mononucleosis. This Epstein-Barr virus infection is the classic cause of a swollen spleen in teenagers and young adults. It comes with a sore throat, swollen glands and heavy tiredness.
- Other viral infections such as hepatitis and HIV.
- Bacterial infections such as endocarditis, an infection of the heart lining, and tuberculosis.
- Parasites such as malaria, which is a common cause in regions where malaria is present.
Liver disease
Cirrhosis and chronic hepatitis scar the liver, which raises pressure in the vein that carries blood from the spleen to the liver. Blood backs up and the spleen swells. This is one of the most common causes in adults, and it is why foods that protect the liver matter for the spleen too.
Blood disorders and blood cancers
- Hemolytic anemias and sickle cell disease, where red blood cells break down early and the spleen has to clear them.
- Leukemia, lymphoma and myeloproliferative disorders, where abnormal blood cells collect in the spleen.
Other causes
- Autoimmune conditions such as lupus, rheumatoid arthritis and sarcoidosis.
- Inherited metabolic conditions such as Gaucher disease and Niemann-Pick disease.
- A blood clot in the veins of the spleen or liver.
- A cyst or abscess inside the spleen, which is uncommon.
Signs the spleen is enlarged
An enlarged spleen often causes nothing you would notice. The NHS and the Mayo Clinic list the same handful of symptoms when it does:
- Pain or a feeling of fullness under the left ribs that may spread to the left shoulder
- Feeling full quickly after eating very little
- Tiredness and pale skin from anemia, because the spleen is removing too many red blood cells
- Catching infections more often
- Bruising or bleeding more easily
Doctors can often feel an enlarged spleen by pressing under the left ribs. A blood count, an ultrasound or a CT scan confirms the size and starts the search for the cause.
Spleen pain in women
A lot of people search for spleen pain symptoms in women specifically, so it is worth saying plainly: the spleen sits in the same place and hurts in the same way in women and men. What differs is which causes are more common.
- Autoimmune conditions such as lupus and rheumatoid arthritis affect far more women than men, and both can enlarge the spleen.
- Iron deficiency and other anemias are more common in women of childbearing age. Some types make the spleen work harder, and the tiredness that goes with anemia can be the first thing noticed.
- Pregnancy does not usually cause spleen pain, but a growing uterus pushes organs upward, so pressure under the left ribs late in pregnancy is more often the stomach or bowel than the spleen. Any sharp, sudden left upper pain in pregnancy still needs same-day assessment.
- Things that are not the spleen. Pain lower on the left side in women is more often the bowel, an ovarian cyst, or a urinary infection. Pain that tracks with the menstrual cycle is not the spleen.
The warning signs are the same for everyone: sudden severe pain under the left ribs, left shoulder pain, dizziness, or a racing heart means emergency care.
Spleen pain after eating
An enlarged spleen sits right next to the stomach. When the stomach fills, it presses against the swollen spleen, so pain or a heavy, full feeling under the left ribs that comes on during or soon after a meal is a classic sign of enlargement. Many people also notice they cannot finish a normal plate of food. Burning pain in the center of the upper abdomen after eating is more likely acid or gastritis, and cramping lower down that eases after a bowel movement is more likely the gut. If meals reliably bring on pain under the left ribs, mention that to your doctor, because it points toward the spleen rather than the stomach.
When spleen pain is an emergency
A ruptured spleen is a tear in the spleen’s surface that causes bleeding into the abdomen. The Mayo Clinic ruptured spleen guide describes it as a medical emergency that can be life-threatening without treatment. It usually follows a hard blow to the left side of the body in a car crash, a contact sport or a fall. An enlarged spleen is softer and more exposed, so it can rupture with much less force, sometimes with none at all.
Go to the emergency department, or call emergency services, if you have:
- Sudden severe pain in the upper left abdomen
- Tenderness when the area is touched
- Pain in the left shoulder, especially when lying down
- Lightheadedness, dizziness, confusion or fainting
- A fast heartbeat or pale, clammy skin, which can signal internal bleeding
The NHS adds a detail many people do not know: a damaged spleen can rupture days or even weeks after the original injury. If you took a hit to the left ribs recently and now have these symptoms, mention the injury.
How doctors find the cause
The MedlinePlus advice is simple: seek medical help right away if belly pain is severe or gets worse when you take a deep breath. For pain that is milder, see your doctor within a few days rather than waiting it out. Expect:
- A physical examination, feeling under the left ribs for the edge of the spleen.
- Blood tests to check red cells, white cells and platelets, and to look for infection, liver problems and blood disorders.
- An ultrasound or CT scan to measure the spleen and look for damage, cysts or clots.
- Further tests if needed, such as a bone marrow test if a blood cancer is suspected.
How spleen pain is treated
There is no treatment for the spleen on its own. Treatment is aimed at whatever made it swell, and the Cleveland Clinic notes that in many cases the spleen returns to normal size as the underlying condition improves.
- Infections such as mononucleosis settle with rest and time. Bacterial and parasitic infections are treated with medication.
- Liver disease is managed by treating the cause, stopping alcohol, and protecting the liver.
- Blood disorders and cancers are treated by a specialist, and the spleen shrinks as the condition is controlled.
- Removal of the spleen (splenectomy) is reserved for cases where the spleen is badly damaged, ruptured, or causing serious problems that cannot be controlled. People who have it removed can live normally, but they have a lifelong higher risk of serious infections and need vaccines and, often, preventive antibiotics.
While the spleen is enlarged, protect it. Avoid contact sports and heavy lifting until your doctor clears you, eat small meals if you feel full quickly, and report new tiredness, bruising or infections.
The bottom line
Spleen pain is felt under the left ribs, can spread to the left shoulder, and gets worse with deep breaths. It almost always means the spleen is enlarged, and the common reasons are infections like mononucleosis, liver disease, and blood conditions. Many enlarged spleens cause no pain and are found by chance.
Mild, steady discomfort should be checked by a doctor within days. Sudden severe pain with dizziness, a racing heart or left shoulder pain, particularly after an injury, needs emergency care. Treat the cause and the spleen usually takes care of itself.
Frequently asked questions
Where exactly is spleen pain felt?
In the upper left part of the abdomen, just under the lower left ribs, and sometimes in the left shoulder. It is often worse when you breathe in deeply or press on the area.
What does spleen pain feel like?
Usually a dull ache or a sense of pressure and fullness under the left ribs rather than a sharp stab. Feeling full after eating only a little is a common companion symptom. Sudden, severe, sharp pain with dizziness is different and points to a rupture.
Can an enlarged spleen hurt without any other symptoms?
Yes, although more often it causes no symptoms at all and is found during an examination. When it does cause symptoms, pain under the left ribs, early fullness when eating, tiredness and frequent infections are the usual ones.
Why does my left shoulder hurt with spleen pain?
The diaphragm, the breathing muscle that sits on top of the spleen, shares a nerve with the left shoulder. When the spleen irritates the diaphragm, the brain can read the signal as shoulder pain. Left shoulder pain with left rib pain after an injury is a warning sign for a ruptured spleen.
Can stress or gas cause spleen pain?
Stress and gas do not affect the spleen, but trapped gas in the bowel near the spleen can cause pain in the same area. Gas pain comes in waves, moves around and eases after passing wind or a bowel movement. Spleen pain is steadier and worse on deep breaths.
Is spleen pain different in women?
No. The spleen is in the same place and the pain feels the same in women and men. What differs is the likely cause. Autoimmune conditions such as lupus and anemia from low iron are more common in women and can both enlarge the spleen. Lower left pain that follows the menstrual cycle is not the spleen.
Why does my spleen hurt after eating?
An enlarged spleen sits against the stomach. When the stomach fills, it presses on the spleen, which causes pain or heavy fullness under the left ribs during or after meals. Feeling full after only a few bites is one of the most common signs of an enlarged spleen and is worth mentioning to your doctor.
How long should I wait before seeing a doctor?
Do not wait if the pain is sudden and severe, worse on deep breaths, or comes with dizziness or a fast heartbeat. That needs emergency care. A milder ache under the left ribs that lasts more than a few days, or comes with early fullness, tiredness or frequent infections, should be checked by a doctor within the week.
