If your scan came back clean and you are still in pain, both of those things can be true at the same time. Soft tissue injuries live in muscle, ligament and tendon, and the imaging you get after a collision is mostly looking for broken bone.
What stands in for the picture is the record you keep. Here is what goes in it, how long to keep it going and what happens if you have not started yet.
Why doesn't a soft tissue injury show up on a scan?
Because of what the scan was built to see.
An X-ray images bone. It cannot show muscle, ligament or tendon in any useful detail, so a clear X-ray after a collision tells you that nothing is broken or out of place. That is an important thing to know and it is good news. It is not an answer to a different question about whether the tissue around the bone has been strained.
MRI and ultrasound can see soft tissue, and they do pick up substantial tears and significant swelling. What they often do not pick up is the more ordinary injury after a collision, a strain or sprain that leaves you stiff and sore for weeks without producing anything a radiologist would flag. A normal result on those scans is not the same thing as a normal neck.
Whether you get that imaging at all depends on what your clinician is looking for. After most collisions the first scan is an X-ray, ordered to rule out a fracture rather than to investigate the soft tissue.
What actually proves a soft tissue injury?
Nothing settles it in one step, and it helps to know that early so you are not waiting on a test that will decide the question for you.
What builds the picture is consistency across three things. What you report, what a clinician finds when they examine you, and what your record shows over time. Each one on its own is thin. Together they describe an injury.
The examination is doing more than it looks like. A physiotherapist is measuring how far you can turn your neck before it stops, which movements reproduce the pain and which do not, and whether the tenderness sits in a pattern that matches how the collision happened. Those findings go into your file and they are exactly the kind of detail a scan cannot produce.
Your own record is the third piece, and it is the only one nobody else can supply. It covers the days between appointments, which is most of them.
What should I write down each day?
Four things, and it takes a couple of minutes.
| What to record | Why it earns its place |
|---|---|
| Pain out of ten, named by body part and by the movement that sets it off | A bare number cannot change in a way anyone can see. Left shoulder, seven, reaching above my head can |
| How many hours you slept and how often you woke | Disrupted sleep is a real loss and it rarely reaches a chart note on its own |
| What you could not lift, carry or turn | Turns pain into a limitation another person can measure |
| Every appointment you went to and the ones you had to cancel | Shows treatment running continuously rather than in pieces |
Write it at roughly the same time each day. Pain moves through the day, so a score taken first thing while you are stiff and a score taken after a long evening of sitting are measuring two different things. Comparing week to week only works if you take the reading at a similar point.
How long should I keep the record going?
Until your treatment finishes, and a little way past it.
Six weeks is roughly where a record stops being a list and starts being a pattern. Three months is where a pattern becomes a trajectory, showing whether you are improving steadily, levelling off or going backwards. Those are three different recoveries and they are hard to tell apart from memory.
If you stop the day you start feeling better and the symptoms return a month later, the empty stretch in between is the part that becomes hard to describe afterwards. A line a week through a good spell keeps the thread unbroken and costs you almost nothing.
What if I have not written anything down yet?
Start today. A record that begins today is a dated record, and it grows forward from wherever you start it.
There is no need to reconstruct the weeks behind you in detail. It is worth writing down what you do remember about the first days, particularly the date of the collision and when each symptom first appeared, and marking those entries clearly as remembered rather than recorded at the time. That distinction is an honest one and it protects the rest of your record.
If you were a passenger rather than the driver, you may be starting with very little written down at all. Our piece on whether a passenger has a claim covers where to begin.
What your care team does with it
Your medical team will ask how things have been since your last visit. It is a hard question to answer well, because the worst moment of the week is the one that stays with you and it crowds out the four days that were manageable.
Handing over a week of dated entries changes that conversation. Your physiotherapist can see which movements are improving and which are not, and can adjust what you are working on rather than starting from a general impression. Those same notes are the ones your claim is built from later, but the first thing they do is make your treatment better.
Deadlines for reporting and for applying for benefits are set separately by each province and territory, and some of them are short. Our page on the first 72 hours sets out what needs to happen early on.
Hurt Square publishes recovery guides for you to document your injury and recovery. The National MVA Recovery Guide works anywhere in Canada, and the Companion Guide for your province adds the deadlines, forms and contacts that apply where you live. The two are built to be used together.
