Bundle of nerve fibres connecting the spinal cord with a spinal nerve. Injury can produce symptoms in a characteristic distribution.

Understanding the structure and its role
Dorsal roots mainly carry sensory information, while ventral roots carry motor commands among other signals. They unite to form a spinal nerve. Fibers are then redistributed through plexuses, so the territory of a root is not identical to that of a named peripheral nerve.
Symptoms and assessment
Irritation can cause radicular pain. Radiculopathy refers to functional root impairment that may include weakness, sensory loss or reflex change. The level is estimated from a pattern of findings, never from one painful point. Electrodiagnostic testing may complement imaging in selected situations.
Assessment considers symptom onset, distribution, restricted activities and medical history. Imaging findings must be compared with the clinical examination: a visible abnormality does not, on its own, establish the source of pain.
Management and outlook
Management distinguishes stable compression from worsening neurological loss. Symptoms may ease before strength fully recovers, so strength needs specific monitoring rather than pain-only follow-up.
For a mechanical problem without concerning findings, care aims for a gradual return to activity, individually selected exercises and measurable functional goals. Manual care may complement this approach when the examination supports it. Progress is judged through walking, sleep and daily tasks, as well as symptoms, rather than through an image alone.
When to seek prompt assessment
New or progressive weakness, newly impaired walking, loss of sensation around the saddle region, or new bladder or bowel control problems require urgent medical assessment.
Frequently asked questions
Are radicular pain and radiculopathy identical?
They can overlap, but pain and neurological loss are distinct concepts.
Can a root be irritated without major compression?
Yes. Inflammatory mechanisms may contribute to symptoms.
Can imaging establish the diagnosis alone?
No. Findings must fit the clinical history and examination before they guide treatment.
Should all activity stop?
Usually not: loading is adjusted and gradually increased according to tolerance and the diagnosis.
How should progress be monitored?
Track functional abilities, neurological symptoms and resumed activities so care can be adjusted.

Role of TAGMED care
At TAGMED, this information helps clarify your history, guide assessment and determine whether conservative care is appropriate or medical referral is needed. An anatomical structure, sign or test result is not, by itself, an indication for decompression, laser, shockwave or manual treatment. Care selection depends on the cause of symptoms and your clinical circumstances.
