You had an injury. The swelling has gone down, the wound has healed and perhaps your scan looks reassuring. So why does the pain still feel like it is there?
This can be confusing, particularly when the pain feels burning, tingling, shooting or unusually sensitive. Sometimes, nerves can remain irritated after an injury even when the original tissue has recovered. But persistent pain does not automatically mean that a nerve has been permanently damaged.
Key takeaways
- Pain can continue after an injury has healed because nerves may remain irritated or sensitised.
- Nerve-related pain often feels different from ordinary muscle or joint pain.
- Persistent symptoms can have several possible causes, so the location and character of the pain matter.
- Assessment may involve checking sensation, strength, reflexes and movement rather than relying on imaging alone.
- Treatment depends on what is causing the symptoms and may not necessarily involve surgery.
Why can pain outlast the injury itself?
Think of nerves as the body’s communication network. They carry signals between different parts of the body and the brain.
After an injury, a nearby nerve may become irritated by swelling, inflammation, stretching or pressure. Even after the original injury has settled, the nerve may continue sending abnormal pain signals for some time.
This is different from saying that the nerve is permanently damaged. Some nerve-related discomforts may include,
- Burning or electric-shock-like pain
- Pins and needles or tingling
- Numbness or altered sensation
- Pain from light touch that would normally not hurt
- Shooting pain travelling along an arm or leg
The pattern matters. A sharp pain that occurs when you move a joint may have a different explanation from a burning sensation that travels along a particular part of the limb.
Could something other than the nerve be causing the pain?
Yes. This is where things can become less straightforward.
Pain after an injury can come from more than one structure. Depending on the original injury, possibilities may include ongoing inflammation, scar tissue, a joint or tendon problem, altered movement patterns or nerve irritation.
Two people can recover from similar injuries and still have different symptoms. That is one reason a doctor may want to understand exactly where the pain starts, where it travels and what makes it better or worse.
An examination may look at,
- Muscle strength
- Sensation and areas of numbness
- Reflexes
- Joint movement
- Tenderness and pain patterns
- How the affected limb moves
Imaging or nerve-related tests may be considered when the clinical assessment suggests they could provide useful information.
When might nerve pain treatment be considered?
The answer depends on the underlying cause rather than simply how long the pain has lasted.
For some people, symptoms may improve as the irritated nerve settles. Others may need treatment directed at the underlying problem. Depending on the findings, management may include medication, physical rehabilitation, activity modification or other approaches.
In selected cases where a nerve is being compressed or another structural problem is identified, a procedure or surgery may be considered. There is no single nerve pain treatment that is appropriate for everyone. The aim is to identify what is producing the pain before deciding what should be done about it.
Should persistent pain after an injury be checked?
If pain continues, changes, interferes with normal activities or is accompanied by increasing numbness or weakness, a medical assessment can help clarify what is happening.
For patients, seeing a doctor who can assess the original injury alongside the current nerve-related symptoms may be useful when the recovery does not seem to be following the expected course.
Frequently Asked Questions
- Does nerve pain always mean permanent nerve damage?
No. Nerves can be irritated or sensitised without having permanent damage. An assessment is needed to understand the cause of persistent symptoms. - What does nerve pain usually feel like?
It may feel burning, tingling, numb, shooting or electric. However, symptoms can vary, and these sensations alone cannot confirm a nerve problem. - Can nerve pain happen after a minor injury?
It can. The severity of the original injury does not always tell you exactly how symptoms will feel during recovery. - Will I need an MRI or nerve test?
Not necessarily. The need for imaging or nerve testing depends on your symptoms and examination findings. These tests are usually considered when they are likely to add useful information.
Schedule a consultation
Persistent pain deserves to be understood rather than simply ignored. It may involve an irritated nerve, another part of the original injury or an entirely different source of pain.
If you are in Singapore and your symptoms have continued despite the injury appearing to heal, consider arranging a consultation with the team of doctors at Surgiten for an individual assessment. The findings can help determine whether further investigation or treatment is appropriate for your situation.
