You’re stopped at a red light on Route 9 in Framingham when you hear tires screech. A split second later, the car behind you slams into your rear end, throwing your body forward against the seatbelt and snapping your head back into the headrest. Your rear bumper is crushed, the trunk is buckled and won’t close, and a taillight lies in pieces on the road. You climb out, shaken, swap information, and tell the officer you’re fine. You were just in a car accident but have places to be. So, you skip the doctor.
It’s one of the most common decisions people make after a crash, and one of the costliest. Here’s why getting checked out quickly matters, both for your health and for your right to be compensated.
Car Accident Injuries Are More Common Than You Think
According to the National Highway Traffic Safety Administration, an estimated 2.44 million people were injured in U.S. motor vehicle crashes in 2023 — roughly five people every minute.
Many of those injuries come from crashes that look minor. A study of 105 low-speed rear-end collisions, where the struck vehicle’s speed changed by an average of only about 4 mph, found that the 113 people involved were diagnosed with 427 injuries within five weeks, mostly to the neck and back. A 2026 analysis of vehicle event data recorders found the chance of a minor injury like whiplash was roughly 30% to 50% even at the lowest impact speeds. In other words, little damage to your car does not mean little damage to you.

Why You May Not Feel Hurt Right Away
A car crash triggers your body’s fight-or-flight response. Adrenaline floods your system and can temporarily suppress pain, so you may feel shaken but otherwise okay at the scene. As the adrenaline wears off over the next several hours, and as inflammation in injured muscles, ligaments and joints builds over the next day or two, symptoms often appear. Whiplash, back injuries, herniated discs and concussions are all known for delayed onset.
Delayed Symptoms to Watch For After a Crash
• Neck pain or stiffness, or trouble turning your head
• Headaches, especially at the base of the skull
• Back, shoulder or jaw pain
• Numbness or tingling in your arms, hands or legs
• Dizziness, fatigue, brain fog or trouble concentrating
• Anxiety, irritability or trouble sleeping
Waiting Gives the Insurance Company an Argument
Many injured people try to tough it out, hoping the pain will go away. Weeks or even months later, when it hasn’t, they finally see a doctor. By then, the insurance company has what it needs to push back.
The argument goes like this: “If you were really hurt in the crash, you would have gone to a doctor right away.” Then the adjuster looks for something else to blame. In cases I have handled, adjusters have argued that a client’s injuries came from going to the gym, doing household chores, or playing basketball — anything except the crash their insured driver caused. Every day without medical care gives them more room to make that argument.
Where do adjusters get these details? In several of those cases, straight from our clients’ own social media posts. A gym check-in, a photo of a freshly mowed lawn, a video from a pickup game — a single post can be taken out of context and used against you, even if you were in pain the whole time. That’s why I always tell clients to stay off social media after a crash while a claim or case is open.
Insurance Companies Are Not on Your Side
Insurance companies are big businesses. Like any business, they are focused on their bottom line, and every dollar they pay on a claim is a dollar off their profits. Adjusters can be friendly and sound helpful, but their job is to close your claim for as little as possible. Offers that sound fair often aren’t.
Arguing that your injuries weren’t caused by the accident is one of the most effective ways they minimize what they pay. A gap in treatment makes that argument easy. Prompt medical care takes it away.
What to Do After a Crash: Get Evaluated Within 24 to 48 Hours
Ideally, seek medical attention the same day as the crash. If that isn’t possible, go within 24 to 48 hours. An emergency room, urgent care center or your primary care provider are all good options. When you’re seen:
- Tell the doctor or nurse practitioner you were in a car accident, and when it happened.
- Describe every symptom, even ones that seem minor or unrelated.
- Follow the treatment plan and keep your follow-up appointments.
- Go back if symptoms change or new ones appear.
What You Say Becomes Evidence
Your words are memorialized in your medical records. A note that says your pain started after the car accident is exactly the evidence lawyers like me need to protect your rights and fight for the compensation you deserve. Without it, it’s your word against the insurance company’s.

Frequently Asked Questions
How soon should I see a doctor after a car accident?
Ideally the same day. If that is not possible, get evaluated within 24 to 48 hours. Prompt care protects your health and creates a medical record that connects your injuries to the crash.
Can car accident injuries show up days later?
Yes. Adrenaline can mask pain for hours, and inflammation from soft-tissue injuries such as whiplash often builds over the next one to three days. Headaches, neck stiffness, back pain, numbness and trouble concentrating commonly appear after the fact.
Will the insurance company deny my claim if I waited to see a doctor?
A delay does not automatically end a claim, but it gives the insurer an opening to argue that something else, such as a workout, yard work or a pickup game, caused your pain. The longer the gap, the harder that argument is to overcome.
I already waited. What should I do now?
See a doctor or nurse practitioner as soon as possible, tell them about the crash and every symptom you have had since, and talk to a personal injury lawyer. Delays can sometimes be explained, but the sooner care begins, the better.
Why does a doctor visit matter for a Massachusetts injury claim?
Massachusetts is a no-fault (PIP) state, and to bring a claim for pain and suffering against the at-fault driver, you generally must meet a legal threshold, such as more than $2,000 in reasonable medical expenses or certain serious injuries like a fracture. Medical records are the proof.
