23 Sep Internal Injuries After a Slip and Fall and How to Recognize Them
Internal injuries are injuries to organs, blood vessels, or tissue inside the body that often leave no visible wound. The most common ones after a slip and fall are spleen and liver tears, kidney damage, bleeding around the brain, and lung injuries from broken ribs. You recognize them by symptoms rather than by sight. Spreading bruises, a rigid or swollen belly, dizziness, confusion, and pain that grows worse over hours are the main warning signs. Because these injuries bleed slowly, a person can feel fine at the scene and be in danger by nightfall. Learning the signs of internal injuries after a slip and fall accident helps you catch the problem while it is still treatable.
Internal Injuries That Happen Most Often
Falls transfer force to whatever lands first. These four injuries account for the most serious internal damage.
Spleen and Liver Lacerations
Both organs sit high in the abdomen and tear easily under blunt force. A torn spleen often causes upper left belly pain, while a liver tear causes pain on the right. Left shoulder pain with no shoulder injury is a classic clue — blood from a ruptured spleen irritates the diaphragm and sends pain up to the shoulder.
Bleeding Around the Brain
A head strike can tear small veins between the skull and the brain. Subdural bleeding is common in older adults and may take one to three days to show. Watch for a headache that keeps building, repeated vomiting, slurred speech, uneven pupils, or unusual sleepiness. Any of these after a head impact is an emergency.
Lung and Chest Injuries
Broken ribs can puncture a lung or tear vessels in the chest wall. Air or blood then fills the space around the lung and makes breathing harder. Signs include shortness of breath, sharp pain on inhaling, and a bluish tint to the lips. Coughing up blood points to direct lung damage.
Kidney and Bladder Damage
Landing on the lower back or hip can bruise or tear a kidney. Bladder injuries are more likely if the fall happened on a full bladder. Blood in the urine is the clearest sign. Deep flank pain, lower belly swelling, and trouble urinating often appear with it.
Symptoms That Point to Internal Bleeding
Some signs apply no matter which organ is hurt. They come from blood loss itself.
- Dizziness or fainting, especially on standing.
- A fast heartbeat paired with cool, pale, or clammy skin.
- Abdominal swelling, tightness, or tenderness on light pressure.
- Deep purple bruising that spreads over hours.
- Vomit that looks like coffee grounds or stool that is black.
When Symptoms Usually Appear
Timing is part of recognition. Slow bleeds follow a pattern that catches people off guard. The first few hours often bring only soreness and mild nausea. Abdominal and chest symptoms usually sharpen within 6 to 24 hours as blood collects. Brain bleeds are the slowest — symptoms can surface two or three days after the fall, especially in people taking blood thinners.
How Doctors Confirm the Diagnosis
A physical exam alone misses many internal injuries. Imaging is what settles the question.
- CT scan: the standard test for abdominal, chest, and head bleeding.
- FAST ultrasound: a quick bedside scan that finds free blood in the abdomen.
- Blood work: a dropping red blood cell count signals ongoing bleeding.
- Urinalysis: detects blood that is not visible to the eye.
Under the federal EMTALA law, 42 U.S.C. § 1395dd, hospitals with emergency departments must screen everyone who arrives, regardless of ability to pay.
Key Takeaways
- Internal injuries usually leave no visible wound after a fall.
- Spleen, liver, brain, lung, and kidney damage are the most common.
- Left shoulder pain can mean a ruptured spleen.
- Blood in the urine suggests kidney or bladder injury.
- Worsening headache, vomiting, or confusion signals bleeding in the skull.
- Dizziness, fast pulse, and pale skin point to active blood loss.
- Brain bleeds may take two to three days to show symptoms.
