What Is Nerve Pain? A Physical Therapist’s Guide to Understanding Neuropathic Pain

Apr 24

If you’ve ever been told you have “radiculopathy” or “neuralgia” and walked out of the doctor’s office more confused than when you walked in, you’re not alone. Nerve pain comes with a vocabulary that can feel like a foreign language — but understanding the difference between these terms can actually help you make better decisions about your care.

Here’s a plain-English breakdown of the most commonly confused nerve pain terms:

Radiculopathy refers to actual pathology — meaning damage or dysfunction — at a nerve root. This is what’s happening when a disc herniation compresses a nerve as it exits the spine.

Radicular pain is pain that travels along the path of a nerve root. The classic example is sciatica — sharp, shooting pain that runs from the lower back down the leg.

Radiating pain is similar but slightly different: it means pain that originates in one location and travels to a distant area — but the cause is at the original site, not necessarily at a nerve root.

Referred pain is when a problem in one area causes pain to be felt somewhere else entirely, without the pain “traveling” there. A tight hip muscle causing knee pain is one example.

Neuropathy means pathology of a nerve itself — anywhere along its path, not just at the root.

Neuralgia specifically refers to pain that comes from a nerve — often described as burning, stabbing, or electric.

Why does this matter? Because the words your provider uses shape the tests they order, the treatments they recommend, and how you understand your own body.
