The Injuries You Cannot See Are Often the Most Dangerous
There is no cast, no visible wound, and frequently no pain at the scene. A person walks away from a collision on Keystone Parkway, declines the ambulance, drives home, and collapses six hours later from a bleed nobody knew about.
Internal injuries are dangerous medically because they are silent, and difficult legally for exactly the same reason. Any delay between the incident and the diagnosis becomes the insurer’s argument that something else caused it.

What Internal Injuries Look Like
Solid organ lacerations. The spleen and liver are the most commonly injured organs in blunt trauma. A splenic laceration can bleed slowly for hours before symptoms appear, and splenectomy carries lifelong consequences for immune function.
Kidney injury, often signaled by blood in the urine or flank pain.
Bowel and mesenteric injury, which is notoriously difficult to detect on initial imaging and can lead to sepsis if a perforation is missed.
Pulmonary contusion and pneumothorax, where the lung is bruised or collapses, sometimes developing over the first 24 to 48 hours.
Cardiac contusion from steering column or airbag impact.
Retroperitoneal and intra-abdominal bleeding, which may not produce obvious external bruising.
Diaphragm rupture, uncommon but frequently missed.
Seat Belt Syndrome
The seat belt saves lives, and it also concentrates enormous force across a narrow band of the abdomen and chest.
A visible bruise along the belt line, sometimes called a seat belt sign, is a recognized marker of possible underlying injury. It should prompt imaging even in a patient who feels fine, because the pattern is associated with bowel, mesenteric, and lumbar spine injury.
If you have a belt-line bruise after a crash, say so specifically at the emergency department. It changes the workup.
Warning Signs After Any Crash or Fall
Seek immediate care if you notice:
- Abdominal pain, tenderness, swelling, or rigidity
- Deep or spreading bruising, particularly along the belt line
- Dizziness, lightheadedness, fainting, or unusual weakness
- Rapid heartbeat with pale, cool, or clammy skin
- Shortness of breath or pain on breathing
- Blood in urine or stool, or vomiting blood
- Pain in the left shoulder, which can signal a splenic bleed
- Persistent nausea
These can appear hours or days later. Adrenaline and, in some cases, pain medication for a more obvious injury can mask them entirely.
How These Injuries Happen in Carmel
High energy impacts. Truck collisions on US 31 and I-465. Roundabout and intersection side impacts, where lateral loading compresses the abdomen against the door. Unbraked rear-end collisions. Motorcycle, bicycle, and pedestrian impacts. Falls from height on construction sites and hard-surface slip and fall incidents.
Patients are typically taken to IU Health North Hospital or Ascension St. Vincent Carmel, with significant trauma often transferred to a Level I center in Indianapolis.
The Delayed Diagnosis Argument
Expect the insurer to argue that because you were not diagnosed at the scene, the injury came from something else: a prior condition, a subsequent event, or nothing related to the collision at all.
Medicine answers that argument, not insistence. Treating physicians can explain why a splenic laceration presents late, why bowel injury is frequently missed on initial CT, and why a patient with a distracting orthopedic injury may not report abdominal pain for a day. Emergency records, imaging sequences, and operative notes tell that story clearly when someone assembles them properly.
What helps most is what you do at the time: get evaluated promptly, report every symptom including vague ones, and return if anything changes.
What These Claims May Cover
Emergency treatment, imaging and diagnostics, emergency surgery, intensive care, blood transfusion, extended hospitalization, follow-up procedures and revisions, long-term consequences such as immune compromise after splenectomy or dietary and medication management after bowel resection, future medical monitoring, lost wages during a lengthy recovery, diminished earning capacity, pain and suffering, and scarring from surgical incisions.
Severe cases overlap with catastrophic injury, and untreated internal bleeding is a leading cause of fatal outcomes after crashes that initially appeared survivable without incident.
Deadlines
Under Indiana Code 34-11-2-4, you have two years from the date of injury, and two years for wrongful death. Comparative fault under Indiana Code 34-51-2-6 applies.
What to Do in the First 24 Hours
If you were in any significant collision or fall, accept the emergency evaluation even if you feel able to decline it. Tell the provider the mechanism specifically: what struck what, at what speed, and whether you were belted. Mention any belt-line bruise, however faint.
Then pay attention for the next two days. If you develop abdominal pain, swelling, dizziness, fainting, unusual weakness, shortness of breath, or left shoulder pain, return immediately rather than waiting for a scheduled follow-up. Emergency departments would far rather see a patient twice than miss a slow bleed.
Keep the discharge paperwork. It documents what was and was not evaluated, which matters later when an insurer argues the injury must have come from something else.
Frequently Asked Questions
How long after a car accident can internal bleeding show up?
Symptoms can appear hours or even a day or two later. Splenic and liver lacerations often bleed slowly at first, and adrenaline suppresses pain at the scene. Warning signs include abdominal pain or swelling, dizziness or fainting, rapid heartbeat with pale, clammy skin, and left shoulder pain. Any of these after a collision warrant immediate emergency evaluation.
What is seat belt syndrome?
It describes the pattern of injuries caused by the belt itself concentrating crash forces across the abdomen and chest. A visible bruise along the belt line is a recognized marker for possible underlying bowel, mesenteric, or lumbar spine injury, and it should prompt imaging even in a patient who otherwise feels well. Mention it specifically at the emergency department.
The insurance company says my internal injury was not caused by the crash. How do we prove it?
With medical evidence rather than argument. Treating physicians can explain why these injuries present late and why initial imaging can miss them. Emergency records, the imaging sequence, and operative findings usually establish causation clearly when assembled properly. Prompt evaluation and complete symptom reporting at the time strengthen this considerably.
I felt fine at the scene and went to the hospital the next day. Does that hurt my claim?
It gives the insurer an argument, but it does not end your claim. Delayed presentation is medically normal for internal injuries and is well documented. What matters is that you sought care as soon as symptoms appeared, described them accurately, and connected them to the collision in the record.
What long-term problems follow an internal injury?
It depends on the organ. Splenectomy carries lifelong increased infection risk and a vaccination schedule. Bowel resection can require permanent dietary and medication management. Lung injury may leave reduced capacity. These future consequences belong in the claim and are frequently omitted when someone negotiates alone.
