It’s not just “shock.” Learn why neck injuries cause hand numbness (Cervical Radiculopathy) and how to fix it without surgery.
You were in a car accident a few days ago. You expected a stiff neck or a headache. But now, you’re feeling something stranger.
Maybe it’s a “pins and needles” sensation in your fingertips when you type. Maybe your arm feels “heavy” or “asleep” when you try to sleep. Or perhaps you’ve noticed you’re dropping things, like your coffee cup or keys.
If you are Googling “why do my hands tingle after a car accident,” we have important news: The problem is likely not in your hands. It is in your neck.
At CT Physical Therapy Care in Queens, this is one of the most common—and overlooked—symptoms we treat. In this guide, we’ll explain why your hands hurt, how to tell if it’s serious, and why waiting too long can jeopardize your New York No-Fault insurance coverage.
The “Garden Hose” Effect: Understanding Nerve Pain
To understand why your fingers are tingling, you have to look at your anatomy.
Your neck (cervical spine) contains seven vertebrae. Between these vertebrae, nerves exit your spinal cord and travel down your shoulder, through your arm, and all the way into your fingertips.
Think of your nerves like a garden hose. If water is flowing freely, the hose works perfectly. But if you step on the hose near the faucet (your neck), the water stops flowing at the nozzle (your hand).

During a car accident—even a low-speed “fender bender” on Queens Boulevard, New York—your head is whipped back and forth violently. This force can cause:
- Disc Herniation: The cushion between your vertebrae bulges out and presses on the nerve.
- Inflammation: Swollen muscles from whiplash squeeze the nerve.
This compression is called Cervical Radiculopathy. Your brain interprets this pressure as numbness, tingling, or burning in your hand.
The Self-Check: Which Finger Is Tingling?
Did you know the location of the tingling can tell us exactly which part of your neck might be injured? Doctors use “dermatomes” (nerve maps) to diagnose injuries.
You can try this simple check at home (but remember, this is not a medical diagnosis):
- Thumb & Index Finger: This often points to the C6 Nerve Root.
- Middle Finger: This usually indicates the C7 Nerve Root.
- Pinky & Ring Finger: This area signals the affected C8 Nerve Root.
If you can pinpoint exactly which fingers are numb, it is a strong sign of a physical injury in your neck, not just “stress” or “shock.”
3 Red Flags: When to Go to the ER
A physical therapist can treat most nerve pain. However, some symptoms indicate a medical emergency.
Go to the Emergency Room immediately if you experience:
- “Saddle Anesthesia”: Numbness in your inner thighs or groin area.
- Loss of Bathroom Control: Inability to control your bladder or bowels.
- Major Weakness: If you suddenly cannot lift your arm, or your hand won’t grip.
These could be signs of spinal cord compression, which is far more serious than a pinched nerve.
Why “Waiting It Out” is Dangerous (Especially in NY)
Many patients tell us, “I thought the tingling would go away, so I waited two weeks.”
We understand. But in New York, waiting is a risk for two reasons:
1. The Physical Risk (Permanent Damage)
Nerves are fragile. If a nerve is compressed for too long, the protective coating (myelin) can wear away. What starts as temporary tingling can turn into permanent muscle weakness or chronic pain. The sooner we take pressure off the nerve, the faster it heals.
2. The Financial Risk (The NY 30-Day Rule)
New York is a No-Fault state. To have your medical treatment covered by insurance, you must file your claim (Form NF-2) within 30 days of the accident.
If you ignore the tingling for 5 weeks and then try to see a doctor, the insurance company may deny your claim. They might argue your hand pain is from “using a computer” or “sleeping wrong,” not the accident.
Documentation is your best defense. Seeing a specialist early creates a paper trail linking your numbness directly to the crash.

How We Treat “Whiplash Nerves” Without Surgery
The good news? You likely don’t need surgery. At CT Physical Therapy Care, we treat cervical radiculopathy using non-invasive, evidence-based techniques.
Our goal is to create space in your neck so the nerve can breathe.
- Manual Traction: We gently stretch the neck to open the spaces between vertebrae, taking immediate pressure off the nerve.
- Nerve Glides (Flossing): Just like floss cleans between teeth, these specific movements help the nerve slide freely through the muscles without getting stuck.
- Posture Correction: We fix the “forward head” posture that often makes whiplash symptoms worse.
Don’t Guess With Your Nerves
Numbness is your body’s “Check Engine” light. It is telling you that something is wrong with the wiring.
If you live in Woodside, Astoria, Jackson Heights, or Sunnyside, don’t wait to see if it gets better.
Contact CT Physical Therapy Care Today, or call us to schedule a comprehensive evaluation. We can test your grip strength, reflexes, and sensation to determine if your accident caused nerve damage—and help you fix it before it becomes permanent.
Frequently Asked Questions
Can nerve damage from a car accident show up later? Yes. This is called “delayed onset” symptoms. Inflammation takes time to build up. You might feel fine the day of the crash, but wake up with numb hands 3 or 4 days later. Read more about Delayed Pain Here.
Does a tingling hand mean I have a concussion? Not necessarily, but they often happen together. If you have tingling plus dizziness or brain fog, you should be evaluated for both. Check our guide on Dizziness and Brain Fog.
Will my car insurance cover physical therapy for nerve pain? In New York, No-Fault insurance generally covers physical therapy if it is medically necessary and related to the accident. We can help you understand your coverage.
