Whiplash: symptoms, recovery, and Florida’s 14-day PIP rule

By Dr. Jeremiah Carlson, chiropractic physician · Jacksonville, FL · Reviewed Nov 2026

Short answer: Whiplash is a neck injury from a rapid back-and-forth motion, most often in rear-end crashes. Symptoms like neck pain, stiffness, headaches, and shoulder pain often appear hours to days later. Most people improve with time, staying active, and guided exercise and manual care. In Florida, get initial care within 14 days of a crash to keep PIP medical benefits.

Common symptoms

Neck pain and stiffness, reduced range of motion
Headaches at the base of the skull
Shoulder, upper-back, or arm pain; tingling in the arms
Dizziness, fatigue, trouble concentrating, poor sleep

What helps recovery

Research and injury-care guidelines generally favor staying active, reassurance and education, and exercise, often with manual therapy, over rest and neck collars. Recovery time varies. Many people improve over weeks, and some take longer.

The Florida piece

Under s. 627.736, PIP medical benefits generally require initial care within 14 days of the crash. Use our 14-day calculator or the 60-second check.

Imaging, referrals, and your care team

We have good working relationships with orthopedic and neurology groups in Jacksonville and refer when appropriate. An MRI is often an important step in identifying soft-tissue injury after a crash — discs, ligaments, and other tissues that an X-ray does not show. We don’t do imaging in our office. We coordinate it and work with all MRI facilities in Jacksonville. We don’t promise a particular finding or outcome.

We work with everyone involved in the case: patients, insurers, attorneys, and other providers. We work with all attorneys. Do I need an MRI after a car accident?

How we approach it at our clinic

Talk and exam. Dr. Carlson takes your history and checks posture, range of motion, reflexes, strength, sensation, and orthopedic tests.
Imaging only if it’s needed. We don’t take X-rays in our office. If your exam shows you need X-rays, an MRI, or a medical specialist, we refer you out and help coordinate it.
A plan in plain English: what we found, what we recommend, how often, and how we’ll measure progress.
Care that fits you, which may include chiropractic adjustments (manipulation or gentler mobilization), chiropractic physiotherapy (corrective exercise), home exercises, lifestyle and workstation advice, and, when appropriate, acupuncture, dry needling, Graston, cupping, laser therapy, or massage therapy.

Get emergency care (911 or ER) if you have: new weakness in an arm or leg, numbness in the groin or inner thighs, new trouble controlling your bladder or bowels, back pain with fever or unexplained weight loss, or pain after a major fall or crash with numbness or weakness. These can signal problems that need urgent medical care, not chiropractic care first.

When your PIP benefits run out, we bill your health insurance, which keeps your out-of-pocket cost down. Call or text 904-619-2703 to verify.

Questions people ask

How long after a crash can whiplash show up?

Often within 24–72 hours. Some people notice symptoms later.

Should I wear a neck brace?

Soft collars are generally not recommended for routine whiplash because staying gently active tends to help recovery. Follow your provider’s advice if you have a fracture or other injury.

Does PIP cover whiplash treatment?

PIP can cover medically necessary care, including chiropractic care, if initial care happens within 14 days, subject to your policy limits and the $2,500 / $10,000 EMC rule.
