What Is a Pinched Nerve? Symptoms, Treatment and When to Seek Help
Pain travelling down your arm or leg, persistent tingling or an area of numbness can be uncomfortable and worrying. A pinched nerve is one possible cause—but does it always mean you need surgery?
Not necessarily. Understanding your symptoms and identifying what is causing them are the first steps towards finding the right treatment.
What is a pinched nerve?
A pinched nerve occurs when surrounding structures compress or irritate a nerve. In the spine, this can happen when a disc bulges or herniates, when the spaces through which nerves travel become narrower, or when changes in the joints and bones put pressure on a nerve.
Your nerves act like electrical cables, carrying messages between your brain, spinal cord and the rest of your body. Pressure on a nerve can disrupt these messages, causing pain, altered sensation or muscle weakness.
What does a pinched nerve feel like?
Symptoms vary depending on which nerve is affected. They may include:
- Pain that travels into an arm or leg.
- Tingling or a “pins and needles” sensation.
- Numbness or reduced feeling.
- Weakness in the affected muscles.
A pinched nerve in the neck may cause pain that travels into the shoulder, arm or hand. A pinched nerve in the lower back may cause pain that travels into the buttock, leg or foot.
This means you may feel symptoms some distance from where the nerve is being compressed. However, these symptoms can also have other causes, so an assessment is important.
Does a pinched nerve need surgery?
Not always. Some pinched nerves improve with time and appropriate non-surgical treatment.
Depending on the cause and severity of your symptoms, treatment may include medication, physiotherapy, adjustments to daily activities or other non-surgical interventions.
The most appropriate approach depends on your symptoms, examination findings and how you respond to treatment. Persistent pain, worsening symptoms or muscle weakness should not be ignored.
Surgery may be considered when symptoms remain troublesome despite appropriate treatment, or when significant nerve compression causes progressive weakness. The aim is to relieve pressure on the nerve and protect nerve function.
How can your neurosurgeon help?
Your neurosurgeon can assess whether your symptoms are caused by a pinched nerve and explain the treatment options available to you.
This assessment may include discussing your symptoms and checking your strength, sensation and reflexes. When necessary, investigations such as an MRI scan can help identify the location and cause of the compression.
Seeing a neurosurgeon does not automatically mean you need an operation. The aim is to recommend the treatment best suited to your condition, relieve pain and help you return to your normal activities.
When should you seek medical attention?
Arrange an assessment if you have persistent radiating pain, numbness or tingling, particularly if symptoms are worsening or affecting your daily activities. New or worsening muscle weakness needs urgent medical assessment.
Go to your nearest emergency department immediately if you develop:
- New difficulty passing urine, an inability to pass urine, or loss of bladder or bowel control.
- Numbness around the groin, genitals, buttocks or “saddle” area.
- Rapidly worsening or severe weakness.
These symptoms may indicate serious nerve compression and should not wait for a routine appointment.
Take the next step
Ongoing nerve pain deserves attention. An assessment can help identify the cause and guide the most appropriate treatment.
Contact your neurosurgeon to arrange a consultation if you are experiencing persistent symptoms.
