C5 Vertebrae Injury Symptoms: What to Know in New Mexico
What are the symptoms of a C5 vertebrae injury? Most often, the signs are neck pain, weakness in the shoulder or upper arm, and numbness or tingling over the outer upper arm. When the spinal cord is also affected, the signs can be more serious. Only a medical exam and imaging can confirm whether a C5 injury is present. This guide explains the common signs, the symptoms that need emergency care, and what to do after a crash in New Mexico.
If a family member is hurt after a crash and you can't tell what the signs mean, our team can talk it through with you in a free, confidential first consultation. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

Where C5 sits in the spine and why it matters
C5 is the fifth vertebra in the neck, counting down from the skull. It is one of the seven bones of the cervical spine, which sits above the shoulders.
The spinal nerves that leave the spinal column at the C5 level help control parts of the shoulder, the upper arm and some breathing muscles. The nerves that power the breathing muscle come from the C3 to C5 area.
The cervical spine protects the spinal cord, the bundle of nerves that carries signals between the brain and the body. That means an injury at this level can affect the cord, the nerve roots that branch off it, or both. A crash can also hurt more than one spot in the neck, so signs may come from more than one place. This is why two people with a C5 injury can have very different symptoms.
Common symptoms of a C5 nerve root injury
A C5 nerve root injury usually shows up as neck pain, shoulder or upper arm symptoms, and sometimes weakness. Many people notice these signs first in the days after a crash.
Watch for these common signs:
- Neck pain that gets worse with movement, which may spread toward the shoulder or the upper part of the arm.
- Weakness in the shoulder or upper arm, including trouble lifting the arm or bending the elbow.
- Numbness or tingling over the shoulder and outer upper arm.
- Stiffness or less movement in the neck after a crash.
These signs overlap with other neck and shoulder conditions, such as a muscle strain or a separate shoulder injury. You cannot sort out the cause by how it feels alone. A medical exam is how doctors tell the difference. Write down when each sign started.
Symptoms that can point to a C5 spinal cord injury
A C5 spinal cord injury can cause weakness, numbness or loss of movement past the shoulder. The hands, legs or trunk may be affected. This pattern is more serious than a nerve root problem alone.
Doctors look closely at signs such as:
- Changes in feeling or coordination, including trouble with fine hand movements or walking.
- Breathing difficulty or shortness of breath.
- Loss of bladder or bowel control, which signals serious spinal cord involvement.
Severe spinal cord injuries at this level can cause paralysis. You can read more in our spinal cord injury overview.
Signs that need emergency care right away
Trouble breathing, sudden weakness or numbness in the arms or legs, and loss of bladder or bowel control need emergency care right away. Call 911 or go to the nearest emergency room.
Any neck injury after a crash, fall or impact should be checked promptly. This is true even when the person can still walk and talk. Symptoms can change quickly, so early checks matter.
Until help arrives, keep the head and neck still. Avoid moving the person unless they are in immediate danger, such as fire or traffic. Emergency responders are trained to stabilize the neck.
When you reach the medical team, tell them when symptoms began and how they have changed. Those details help clinicians decide which tests to run.
Why symptoms can appear or change after a crash
Neck and nerve symptoms can appear hours or days after a crash. A late start does not rule out a C5 injury.
Symptoms can also shift as swelling changes or as the injury is evaluated. Keep a written symptom log with dates, times and what changed. Bring it to every appointment.
Only a neurological exam and imaging by a qualified medical provider can confirm a C5 injury and show how severe it is. No article, including this one, can replace that evaluation.
New Mexico law also looks at cause. Under Herrera v. Quality Pontiac, a proximate cause is one that, in a natural and continuous sequence, produces the injury. It need not be the only cause.

Next steps if a family member is showing these signs
Get a medical evaluation first. Then write down the symptoms, the date and time of the crash, and who was present.
New Mexico’s accident laws set duties for drivers. A driver in an accident that causes injury must stop and remain at the scene until the duties to give information are done.
Within a municipality, that notice goes to the police department; otherwise, it goes to the county sheriff’s office or the nearest New Mexico state police office.
Many people reading this are helping someone who cannot easily make calls right now. A family member can gather these notes and dates on that person’s behalf.

Common C5 symptoms to watch for
Neck pain
Pain or stiffness in the neck, sometimes after a crash, fall or sudden impact, even when the first days feel mild.
Shoulder or upper arm weakness
Trouble lifting the arm, raising the shoulder or bending the elbow can be an early sign of a C5 nerve problem.
Numbness on the outer upper arm
Tingling or numbness over the shoulder and outer upper arm may point to the C5 nerve root.
Limited neck movement
Reduced range of motion or pain when turning or tilting the head should be checked by a medical provider.
Call 911 now if you notice these signs
Trouble breathing, sudden weakness or numbness in the arms or legs, or loss of bladder or bowel control can signal a serious spinal cord injury. Get emergency care right away. Do not wait for symptoms to pass.
After you get medical care
Get a full medical exam
Imaging and a neurological exam are the way providers confirm a C5 injury and its cause. Follow the treatment plan your doctor gives you.
