Volume I · The cervical spine
Home entry · August 2026 · 11 entriesSeven small bones carry the whole head. Then a car stops suddenly.
The neck is a precise structure asked to survive an imprecise event. A rear-end collision moves the head through an arc it was never built for, in well under a second, and the injury it leaves behind is famously quiet at first. This journal documents how that injury behaves, and what a careful response looks like in the St. Louis metro.
Hazelwood office: (314) 627-1411 · closed daily 12 to 2

Observation one
The physics are not negotiable.
In a rear-end impact the torso is pushed forward by the seat while the head, for a fraction of a second, stays where it was. The cervical spine absorbs the difference. This happens faster than a muscle can brace, which is why bracing did not save you and why feeling fine at the scene proves very little.
The strained tissue swells and stiffens over the following days. That is the ordinary course, not a rare complication. It is also why the exam should happen this week and not whenever the pain becomes undeniable. Entry 02 walks through the mechanism.

The entries
Eleven entries, written in order.
What the neck does in the days after impact
Hour by hour, then day by day: the misleading calm, the stiff morning, the headache that climbs from the base of the skull.

Seven small bones, one sudden stop
Why a low-speed rear-end hit can strain a neck, what the headrest was for, and why bracing did not save you.
Read the entry → 03The delayWhy the neck waits three days to complain
Stress chemistry, swelling on a schedule, and the ordinary reason people feel fine at the scene and terrible on Thursday.
Read the entry → 04The symptomThe headache that starts at the base of the skull
When a post-crash headache comes from the neck, when it does not, and the bright line that sends you to an emergency room instead.
Read the entry → 05The overlapConcussion without a knockout
The neck and the head share the same second of impact. Fog, dizziness, and light sensitivity after a crash deserve their own paragraph on the chart.
Read the entry → 06The aftermathDriving to work with a neck that will not turn
Shoulder checks, desk posture, the drive home. How an untreated neck injury compounds on an ordinary workweek, and what interrupts the pattern.

You do not need to have decided anything about a claim before you get examined. A documented exam this week protects your health and your options.
Get seen this weekObservation two
A precise injury deserves a precise response.
Missouri Injury Clinic, run by Joseph L. Hollingsworth, DC, takes auto-injury patients at three offices in the metro: Hazelwood, Tesson Ferry in south county, and O'Fallon. The response is methodical: an examination, findings recorded, a written treatment plan, and dated visits after that.
A necessary boundary. This journal does not diagnose, and a webpage cannot examine a neck. Severe symptoms, spreading numbness or weakness, and anything involving the head that is worsening go to an emergency room before anything else. Entry 07 explains the first visit.

Featured clinic
Three offices that can see you this week.
Missouri Injury Clinic
Joseph L. Hollingsworth, DC
Putting the CARE back in Healthcare
The clinic publishes three lanes on moinjuryclinic.com: auto injuries, meaning diagnosis and a treatment plan after a crash; TBI and concussion rehab; and sports injuries. If your neck was hurt in a crash, you are in the first lane. If your head was hurt too, say so on the phone; the second lane exists for that.
Pick the office you can actually drive to this week. All three close daily from 12 to 2, so call in the morning or after two. State that it was an auto injury and give the date of the crash. If you already have an attorney, bring their contact so records can be sent where they need to go.

Last line of the home entry
The record that good care produces is the same record the aftermath asks for.
If a claim is ever part of your story, the dated record from the first exam is what everyone will ask for. Pursue the care. The record follows. Everything on this desk is educational and general. It is not medical advice, not a diagnosis, and not a substitute for an examination by a licensed clinician who can see your neck.
