Key Takeaways
- Broad vs. Specific: A 'head injury' is a broad term that encompasses any trauma to the scalp, skull, or brain, whereas a concussion is a specific type of traumatic brain injury (TBI) that affects brain function.
- Visible vs. Invisible: Head injuries often present with visible signs like cuts or bruises, while concussions are internal and characterized by symptoms like confusion, dizziness, and sensitivity to light.
- Severity varies: Not every bump on the head results in a concussion, but all head trauma deserves careful monitoring for delayed symptoms.

You trip on a rug, bump your head on a cabinet door, or take a tumble during a pickup soccer game. It hurts, and maybe there is a bump, but are you fine? Or is it something more serious?
This is the moment where the distinction between a general head injury and a concussion becomes vital. While the terms are often used interchangeably in casual conversation, they mean very different things medically. Understanding that difference is the first step in ensuring you or a loved one gets the right care.
Head trauma is one of the most common reasons people visit the emergency room, yet misconceptions persist. A bloody cut doesn't always mean brain damage, and a person who looks completely fine might be suffering from significant chemical changes in their brain.
Defining the Terms: What is a Head Injury?
Think of 'head injury' as an umbrella term. It refers to any sort of trauma occurring to the scalp, skull, or brain. These injuries can range from a mild bump or bruise (contusion) to a traumatic brain injury.
Doctors typically categorize these into two main buckets:
External Head Injuries
These affect the scalp and the skull but do not necessarily injure the brain itself. The scalp is rich in blood vessels, so even a minor cut can bleed profusely, looking scary without being life-threatening. Common external injuries include:
- Lacerations: Cuts on the skin.
- Contusions: Bruises on the scalp.
- Fractures: Breaks in the skull bone.
Internal Head Injuries
These involve the brain and blood vessels inside the skull. This is where the situation becomes more complex. Internal injuries can include bleeding (hemorrhage), tearing of nerve fibers, or the brain swelling against the skull.
What is a Concussion?
A concussion is a specific category of internal head injury. It is a mild traumatic brain injury (mTBI) caused by a bump, blow, or jolt to the head—or by a hit to the body that causes the head and brain to move rapidly back and forth.
This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in the brain and sometimes stretching and damaging brain cells.
Crucially, concussions are functional injuries, not structural ones. This means that if you get a CT scan or an MRI after a concussion, the images usually come back 'normal.' There is no visible bleed or bruise on the brain, but the way the brain functions has been temporarily disrupted.
Comparing Symptoms: How to Tell Them Apart
Because you cannot see a concussion on a standard scan, diagnosis relies heavily on observing symptoms. A general head injury (like a bruise) hurts at the site of impact. A concussion, however, creates systemic issues that affect how you think, feel, and sleep.
Head Injury vs. Concussion Comparison
| Feature | General Head Injury (External) | Concussion (mTBI) |
|---|---|---|
| Primary Location | Scalp, Skull | Brain |
| Visible Signs | Swelling, bleeding, bruising, cuts | Often none; patient may look 'dazed' |
| Pain Type | Localized (sore to touch) | General headache or pressure |
| Cognitive Impact | Usually none | Confusion, memory loss, 'foggy' feeling |
| Physical Impact | Tenderness at impact site | Nausea, dizziness, balance issues |
| Sensory Impact | None | Sensitivity to light or noise |
When to Seek Emergency Care
Most bumps on the head are minor and heal with a little ice and rest. However, because the brain is involved, you must be vigilant.
If you or someone else experiences any of the following 'red flag' symptoms after a hit to the head, seek emergency medical attention immediately:
- One pupil is larger than the other.
- Drowsiness or inability to wake up.
- A headache that gets worse and does not go away.
- Slurred speech, weakness, numbness, or decreased coordination.
- Repeated vomiting or nausea, convulsions, or seizures.
- Unusual behavior, increased confusion, restlessness, or agitation.
- Loss of consciousness (even for a brief moment).
The Role of Physical Therapy in Recovery
For those who do sustain a concussion, the old advice of 'sit in a dark room until you feel better' is outdated. Modern medical approaches, like those used at [Your Practice Name], emphasize active recovery.
Physical therapy plays a massive role in concussion management. Specialized therapists can help treat:
- Vestibular issues: Reducing dizziness and improving balance.
- Vision problems: Helping the eyes focus and track correctly again.
- Neck strain: Treating whiplash that often accompanies the head impact.
- Exertion training: Safely guiding patients back to exercise and sport without triggering symptoms.
Don't Guess with Your Brain Health
Head trauma is tricky. You might feel fine immediately after an accident, only to have symptoms creep in hours or days later. Whether it is a simple cut that needs stitches or a concussion requiring a managed recovery plan, professional evaluation is the only way to be sure.
Epic Medical is dedicated to keeping Pennsylvania families healthy and active. From concierge primary care to specialized physical therapy, our team can guide you from the initial injury assessment all the way through to full recovery.

Frequently Asked Questions
Can you have a concussion without hitting your head?
Yes. A concussion is caused by the rapid movement of the brain inside the skull. This can happen from a severe jolt to the body, such as whiplash during a car accident or a hard tackle in football, even if the head itself does not make direct contact with an object.
How long does a concussion last?
Most people recover from a concussion within 7 to 10 days. However, recovery times vary significantly depending on age, history of previous concussions, and severity of the injury. Some patients may experience 'post-concussion syndrome,' where symptoms persist for weeks or months.
Is it safe to sleep after a head injury?
In most cases, yes. The old advice to keep someone awake is generally no longer recommended for mild concussions. Sleep is actually vital for brain recovery. However, if the injured person is exhibiting 'red flag' symptoms like vomiting or deteriorating consciousness, they need emergency care, not sleep. Always consult a doctor first.
Do helmets prevent concussions?
Helmets are designed primarily to prevent skull fractures and severe brain injuries (like bleeding). While they offer some protection, they do not prevent concussions entirely because they cannot stop the brain from moving inside the skull during an impact.
