Pressure under left rib cage can have various causes, ranging in severity from 'troubling' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose pressure under left rib cage, we could:
|Valley Fever (Coccidioidomycosis)||5%||Ruled out|
|Congestive Heart Failure||0%||Ruled out|
|Enlarged Spleen||0%||Ruled out|
MIDDLE-LEFT abdomen: Do you experience pressure or 'fullness' below your lower left rib which is painless or slightly tender? (Do not answer this question if there is significant pain.)
Possible responses:→ There is significant pain / don't know
→ Yes, slight pressure with no/slight pain
→ Yes, significant pressure with no/slight pain
Enlarged Spleen also suggests the following possibilities:
In severe failure of the right ventricle, elevated venous pressures are transmitted to the portal system, leading to congestion of the spleen and splenomegaly.
Hypersplenism is sometimes referred to as enlarged spleen (splenomegaly), but in fact an enlarged spleen is one of the symptoms of hypersplenism. What differentiates hypersplenism is its premature destruction of blood cells.
About 50-75% of people with mononucleosis have some spleen enlargement, usually seen two to three weeks after they first become sick. Whether or not the spleen is enlarged, people who have mono should not lift heavy objects or exercise vigorously – especially participating in contact sports – for two months after they get sick, because these activities increase the risk of rupturing the spleen, which can be life-threatening. If you have mono and get a severe sharp, sudden pain on the left side of your upper abdomen, go to an emergency room immediately.
ALL, CML, or hairy cell leukemia can cause enlargement of the spleen.
