When Should You Go to the Doctor After a Car Accident (Denver and Colorado Guidance)

Kelly Geraghty on December 30, 2025

After a car accident in Denver, it is common to feel “okay” at the scene and then wake up the next day feeling sore, stiff, or foggy. The problem is that waiting too long to get checked out can put your health at risk and can also make it harder to connect your injuries to the crash later.

The simple answer

You should consider getting medical care the same day if you have:

  • Headache, dizziness, nausea, confusion, or any “not myself” feeling
  • Neck or back pain, stiffness, or limited range of motion
  • Numbness, tingling, weakness, or shooting pain into an arm or leg
  • Chest pain, abdominal pain, or trouble breathing
  • Any visible injury that is swelling or worsening
  • Any concern you might have hit your head

If you are ever unsure, it is safer to get evaluated.

For the full step-by-step overview of what to do after a Denver crash.

Why symptoms can show up later

After a collision, your body can stay in “adrenaline mode.” That can mask pain and make you underestimate injuries, especially with:

  • Soft tissue injuries (neck, back, shoulders)
  • Concussions and mild traumatic brain injury symptoms
  • Joint injuries (knees, hips, wrists) from bracing or impact

A checkup creates a medical record, documents your symptoms, and helps guide next steps.

Situations where you should get checked out promptly

Some crash types are more likely to cause injuries even when the vehicle damage looks “minor.”

Rear-end crashes

Neck and back injuries are common after rear-end impacts, even at lower speeds.

Side-impact (T-bone) crashes

Side impacts can cause serious injuries because there is less space between you and the point of impact.
Related: Side-impact collision

Head-on collisions

These are often severe and deserve immediate evaluation.
Related: Head-on collision

High-speed and low-speed crashes

High-speed crashes can create obvious trauma. Low-speed crashes can still cause real injuries, even if the car looks fine.

Truck accidents

Commercial vehicle crashes can involve more force and more complex injury patterns.

Rideshare crashes (Uber or Lyft)

If you were a passenger, document symptoms and get checked out. Injury claims can still be heavily scrutinized.

Pedestrians, cyclists, and motorcyclists

Even a “minor” impact can be serious when you have limited protection.

A symptom checklist to take seriously

If you notice any of the following in the hours or days after the crash, consider getting evaluated:

Head and brain symptoms

  • Headache that does not improve
  • Dizziness, balance problems
  • Nausea, vomiting
  • Light or sound sensitivity
  • Trouble focusing, fogginess, memory issues
  • Mood changes, irritability, unusual fatigue

Neck, back, and nerve symptoms

  • Stiffness or pain that worsens overnight
  • Reduced range of motion
  • Radiating pain (down an arm or leg)
  • Numbness or tingling
  • Weakness or grip issues

Chest and abdomen symptoms

  • Chest pain or pressure
  • Pain with deep breaths
  • Abdominal pain or bruising
  • New or worsening shortness of breath

Where to go for care

This depends on symptoms and severity.

Emergency room

Consider the ER if symptoms are severe, worsening, or involve head injury signs, breathing issues, significant chest pain, or serious trauma.

Urgent care

Urgent care can be appropriate for milder symptoms that still need documentation and evaluation.

Primary care

If symptoms are mild and stable, your primary care provider can help document and guide treatment.

No matter where you go, make sure your symptoms and how they started are clearly documented.

Documentation tips that help your health and your claim

This is not about exaggerating. It is about accuracy.

  • Write down symptoms as they appear, including timing (same day vs next day)
  • Save visit summaries, imaging results, and follow-up instructions
  • Track missed work and daily limitations
  • Keep receipts for prescriptions and medical devices

Mistakes to avoid

  • Waiting days or weeks to get evaluated when symptoms start early
  • Telling insurance you are “fine” before you know
  • Skipping follow-up care if symptoms persist
  • Not keeping any record of symptoms, missed work, or limitations
