About traumatic peripheral nerve injury
Nerves can be injured in many ways: a fall that stretches the arm, a fracture near a nerve, a deep cut, or pressure during a long surgery. The injury may range from a temporary stunning of the nerve to a complete break in its fibers. How the nerve recovers depends on the type and severity of the damage.
Mild injuries often recover on their own over weeks to months. More serious injuries recover slowly, because nerve fibers regrow gradually from the injury site toward the muscles and skin. Some complete injuries need a nerve surgeon, and timing can matter, which is why early and accurate testing is valuable.
Common symptoms
- Numbness or altered sensation in the area the nerve supplies
- Weakness or inability to move certain muscles
- Burning, electric, or shooting nerve pain
- Muscle wasting over time in the affected area
- Tingling that moves or changes as the nerve recovers
Common causes and risk factors
- Stretch injuries from falls, sports collisions, or shoulder dislocations
- Fractures or joint injuries near a nerve
- Cuts, lacerations, or penetrating wounds
- Crush injuries or prolonged pressure, including during surgery or casting
How we diagnose it
Dr. Chen reviews how the injury happened and examines strength, sensation, and reflexes to map which nerve is involved. An EMG and nerve conduction study measures how well the nerve is carrying signals and whether muscles are still connected, and nerve ultrasound can show swelling, scarring, or a break in the nerve. Repeat testing over time helps show whether the nerve is recovering, which guides decisions about rehab and surgical referral.
How Propel treats traumatic peripheral nerve injury
Early care protects the limb and keeps you as active as possible. Rehab focuses on keeping joints flexible, strengthening the muscles that still work, retraining sensation, and using braces when a weak muscle needs support. We also address sleep and overall conditioning, since recovery from a nerve injury is a long process and general health supports it.
Nerve pain after injury can be significant, and Dr. Chen may recommend medications or peripheral nerve stimulation, in which a thin lead near the nerve delivers mild electrical pulses to reduce pain. When testing shows a nerve is not recovering as expected, we help coordinate a timely referral to a nerve surgeon, since some repairs work best when done early.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Questions about traumatic peripheral nerve injury
- How long does a damaged nerve take to recover?
- It varies with the type of injury. A mildly stunned nerve may recover within weeks, while a nerve that must regrow its fibers heals slowly over many months. Follow-up testing helps show whether recovery is on track.
- When should nerve testing be done after an injury?
- Some nerve changes take a few weeks to appear on testing, so an EMG is often most informative a few weeks after the injury. Dr. Chen may still see you sooner to examine the limb, start rehab, and use ultrasound to look at the nerve directly.
- Do all nerve injuries need surgery?
- No. Many nerve injuries recover with time and rehab. Surgery is considered when a nerve is cut or shows no signs of recovery on testing, and we help coordinate that referral when it is needed.
