Common Spine Conditions: A Guide to the Terms
Use this overview to understand common spine terms, find related reading and prepare questions for an assessment. A condition name alone does not determine which care is appropriate.
A Starting Point for Understanding Your Symptoms
Content updated .
A spine report can contain several unfamiliar terms. Start by asking what each term describes: a symptom, a change in a structure, or the space available for a nerve. These terms answer different questions and need to be connected with the examination.
One report, several labels: read them by role
- Symptoms: neck pain, back pain and sciatica describe what a person experiences. They do not, on their own, identify every structure involved.
- Disc, joint or ligament findings: a disc bulge, facet-joint change or ligamentum flavum thickening describes a particular part of the spine. Use the linked topic guides below to understand that finding.
- Available space: stenosis describes narrowing. Ask where it is, which nerve structures may be affected and whether the findings match your symptoms.
- Alignment: spondylolisthesis concerns the position of one vertebra relative to another. It is different from a disc bulge or herniation.
For example, a report may describe both disc changes and narrowing; these are different descriptions of what is present, not a count of how many treatments you need. Write down the exact wording, the spinal level and the side mentioned. Ask which findings are relevant to your main difficulty and which may be incidental.
This directory helps you choose the next explanation to read. It is not a list of conditions for which every NSD Therapy® component is suitable. See the NIAMS explanation of narrowing and the structures involved and the imaging evidence discussed below.
When Symptoms Need Emergency Assessment
With back or leg symptoms, new numbness around the genitals or anus, new difficulty starting or passing urine, new bladder or bowel dysfunction, or new sexual dysfunction may indicate cauda equina syndrome. Go to an emergency department immediately. Do not wait for loss of continence, several signs together or a clinic appointment. Rapidly worsening leg weakness also needs urgent medical escalation. Pregnancy does not remove the need for emergency assessment when these signs occur.
See NICE NG127, recommendation 1.7.3 (opens in a new tab). Routine clinic inquiries are not an emergency service.
How I Approach the Assessment
I ask when symptoms started, what changes them, which activities are difficult, what you have already tried and whether strength or sensation has changed. Relevant medical history, medication, previous operations and existing reports also matter.
My examination and discussion guide the next step. This may involve a proposed service, further investigation or another professional opinion. The official MyChiro first-visit guide (opens in a new tab) explains the practice process.

The links below organize related reading. They do not establish a diagnosis or approve a particular treatment.
Symptoms and disc-related terms
- Neck and back pain: start with the symptoms and their effect on everyday activities.
- Disc herniation and bulging disc: terms describing disc shape. A finding may occur with or without symptoms.
- Degenerative disc changes: imaging changes that need to be interpreted alongside the clinical picture.
- Schmorl’s nodes: a separate topic to discuss if this term appears in your report.
Joints, ligaments and alignment
- Posterior facet joint concerns: reading about the small joints at the back of the spine.
- Ligamentum flavum thickening: reading about a supporting ligament and its relationship to available space around nerves.
- Spondylolisthesis: movement of one vertebra relative to another. It is different from a slipped disc.
Radiating symptoms and narrowing
Sciatica usually involves symptoms spreading into the buttock and leg, which can include pain, tingling, numbness or weakness. Back pain alone is not the same symptom pattern. Spinal stenosis describes narrowing of spaces around spinal nerves or the spinal cord; its effects depend on the location and clinical findings.
For independent explanations, see NHS guidance on sciatica (opens in a new tab) and NIAMS on spinal stenosis (opens in a new tab).
Persistent Symptoms After Spine Surgery
Persistent or recurrent symptoms after an operation need a fresh clinical explanation. The phrase “failed back surgery syndrome” does not identify one cause or automatically indicate decompression, manipulation or another procedure.
Tell the practitioner what operation you had, when it took place, whether implants were used and what your surgical team advised. Bring available reports. The presence or absence of hardware, or the number of months since surgery, is not enough by itself to decide whether a procedure is appropriate.
I may need information from the treating surgeon or another medical professional before discussing a plan. New or worsening symptoms should not be dismissed as an expected part of an old back problem.
Connect Each Proposed Option to a Clear Purpose
Ask what each proposed component is intended to change, what evidence supports that purpose, what risks and alternatives apply, and how progress will be reviewed. A non-surgical procedure can still have risks or be unsuitable.
NSD Therapy® is a framework that can coordinate different services. The official MyChiro framework guide (opens in a new tab) explains this relationship. Our effectiveness page addresses evidence questions, while the suitability page focuses on assessment.
Questions About Conditions and Care
Does an MRI finding always explain pain?
No. A systematic review found degenerative findings in many people without symptoms. This does not mean every finding is unimportant; it means that the report needs clinical context. See Brinjikji and colleagues’ 2015 review abstract (opens in a new tab). It studied imaging prevalence, not the effectiveness of NSD Therapy®.
Does my diagnosis mean I need decompression?
No diagnosis on this page automatically selects a device or procedure. Ask how the particular proposal relates to your examination, goals, risks and alternatives. Different components have different evidence and limitations.
Are bulging discs, herniated discs and spondylolisthesis the same?
No. Disc terms describe findings involving the tissue between vertebrae. Spondylolisthesis refers to one vertebra moving relative to another. Ask the clinician to explain the exact report wording and its relevance to your symptoms. The NHS spondylolisthesis guide (opens in a new tab) explains the distinction.
Does listing a condition here mean NSD Therapy® is proven to treat it?
No. This is a topic directory. Evidence for a particular exercise, manual procedure or traction method cannot automatically be applied to the whole branded framework or to every condition. An improvement in pain also does not, by itself, demonstrate structural disc repair.
Will I need surgery, medication or a referral?
That depends on the findings and available options. A website cannot determine the answer. Discuss medical and surgical options when relevant rather than assuming that a non-surgical program can replace them. Do not change prescribed medication on the basis of this page.

Describe the Whole Symptom Pattern
Describe all affected areas, even if the appointment began with one main complaint. Note whether symptoms stay in the neck or back, travel into an arm or leg, or change during walking, sitting, sleep or usual tasks. Do not assume two painful areas necessarily have the same cause.
Make Your Appointment Notes Useful
A short timeline is often more useful than a long list of labels. Write down the onset, important changes, previous care and two or three activities you want to manage better. Distinguish pain from changes in sensation, strength or coordination.
I use these details as a starting point for examination and later review. A home plan, where appropriate, should explain the activity, its purpose, how to adapt it and what changes to report. A general condition page cannot prescribe the same exercises for everyone.
What should I describe about neck and arm symptoms?
State which side is affected, whether symptoms reach the hand or fingers, which tasks are difficult, and whether you have noticed changes in sensation, grip or coordination. Include new symptoms even if you have had neck pain for years.
What should I describe about upper-back symptoms?
Explain the exact area, when the symptom appears and any associated concerns. Do not label chest symptoms as a spinal problem yourself. Sudden chest discomfort that does not go away, chest pain spreading into the arm, jaw or back, or chest pain with breathlessness, sweating or lightheadedness needs immediate emergency medical help. See NHS chest-pain guidance (opens in a new tab).
What should I describe about lower-back and leg symptoms?
Explain whether symptoms affect one or both legs, how far they travel and whether walking or standing has changed. Report new weakness or altered sensation. Follow the emergency guidance above if bladder, bowel, sexual-function or saddle-area sensation changes occur.
How will we decide whether a plan is helping?
I compare current findings and activity goals with the starting point. We discuss what has changed, what remains difficult and whether to continue, adjust, stop or seek another opinion. See our session-planning and review guide.
