Adrenaline can mask injuries for 24–72 hours after a NYC crash. By the time pain emerges, often when you wake up the next morning, the clock is already running on your 30-day no-fault notice window (Form NF-2) and your evidence window is closing. The injuries you discover on day 4 are still legally tied to the crash, but only if you document them properly.
This guide applies to New York State law.
If you're feeling new pain, stiffness, headaches, or memory issues days after a NYC accident:
- 1See a doctor today. Same-day or next-day medical care is essential. Tell the doctor about the accident, every visit creates a medical record connecting your symptoms to the crash.
- 2File NF-2 immediately if you haven't. The 30-day deadline applies even if your injuries are delayed.
- 3Follow through on referrals. Imaging (MRI, CT) within 4–6 weeks is critical for diagnosing soft-tissue and disc injuries.
- 4Keep a symptom journal. Daily notes on pain levels, sleep, and functional limitations support both PIP and the serious injury threshold.

Step 1: Select accident type
What type of accident were you in?
What You're Experiencing
Days or weeks after the NYC accident, you're noticing new pain, stiffness, headaches, dizziness, sleep problems, mood changes, or memory issues that weren't there before.
What This Likely Means
- If you have neck or back pain that started 1-3 days post-crash → Likely whiplash or facet joint injury; MRI within 6 weeks is recommended
- If you have headaches, dizziness, or memory issues → Possible mild TBI or concussion; immediate neurological evaluation required
- If you have leg numbness or radiating pain → Possible disc herniation; orthopedic referral and MRI urgent
- If you have abdominal pain or bruising → Internal injury; ER evaluation immediately
Your Options
You Can Do This
- •See a doctor today and explicitly mention the NYC accident
- •Start a daily symptom journal, pain levels, sleep, functional limits
- •Photograph any visible bruising, swelling, or wounds
- •Save all medical bills, receipts, and pharmacy records
Attorney Handles
- •Files NF-2 within the 30-day window even with incomplete diagnosis
- •Requests medical record documentation that ties symptoms to the crash
- •Coordinates referrals to MRI, neurology, and physical therapy
- •Builds the serious injury threshold case from initial medical evidence
Avoid Doing This
- •Don't refuse the ER visit on the day of the accident
- •Don't delay medical care more than 72 hours
- •Telling a doctor you feel fine while symptomatic ends up in the record insurers read. Describing every symptom, even mild ones, protects the claim.
- •A signed insurance release closes the claim even if symptoms are diagnosed later. Attorneys advise waiting for a complete diagnosis.
What This Typically Costs
MRI in NYC: $1,200–$3,500 without insurance. NY no-fault PIP covers diagnostic imaging when prescribed by a treating physician. Concussion/TBI evaluations average $800–$2,500. Physical therapy in NYC: $150–$300 per session. PIP covers up to $50,000 in medical costs, after which your health insurance or the at-fault driver's lawsuit becomes the source.
When to Get Help
Many situations on this page are manageable on your own. The Your Options section above shows what people commonly handle themselves and where an attorney typically adds value.
These signals usually mean it is time to talk to a licensed attorney:
- 1
If you experience confusion, severe headache, vomiting, or vision changes → Go to the ER immediately. Possible TBI.
- 2
If you have abdominal pain or bruising → ER immediately. Internal injuries can be fatal if untreated.
- 3
If you have new leg numbness or weakness → ER or urgent care. Possible spinal cord involvement.
A consultation is information, not a commitment. Free consultations are standard at New York personal injury firms.

Common Mistakes to Avoid
- 1
Mistake #1: Telling the ER 'I feel fine' and refusing the doctor visit.
The ER record from the day of the crash is foundational. Even if you decline imaging, request that the doctor document the crash, your reported symptoms, and recommend follow-up. A signed AMA (Against Medical Advice) form can be used by insurers to argue you weren't injured.
- 2
Mistake #2: Going to your primary care doctor weeks later without mentioning the crash.
Your records must connect the symptoms to the accident. If you describe your back pain to your PCP without referencing the NYC crash, the medical record won't support your claim.
- 3
Mistake #3: Treating the 30-day no-fault notice window as flexible because you're 'still figuring out how bad you're hurt.'
A late notice is accepted only with written proof of a clear and reasonable justification, so treat the 30 days as firm. File as soon as possible, even if your full diagnosis hasn't emerged.
Frequently Asked Questions
I feel fine after my NYC accident. Should I still see a doctor?▼
Yes. Many accident injuries, concussions, whiplash, disc herniations, internal bleeding, present hours or days later. A same-day medical visit creates the foundational record that connects any future symptoms to the crash. Telling the ER you 'feel fine' and declining a visit can sink an otherwise valid claim.
Can I still file a no-fault claim if my injuries appeared days later?▼
Yes, but the 30-day notice window still applies. File the form immediately upon discovering injuries, even if your full diagnosis hasn't been completed. Delayed symptoms do not extend the 30 days on their own; under 11 NYCRR § 65-1.1 (Reg 68), a late notice is accepted only with written proof of a clear and reasonable justification for the delay.
