Slip Disc Symptoms: Signs, Causes, Warning Signs & More

Quick Glance: Common Slip Disc Symptoms

Slip disc symptoms vary depending on the location of the affected disc and whether it irritates or compresses nearby nerves. Common symptoms include:

Lower back pain
Neck pain
Pain spreading into the buttock, hip, arm or leg
Tingling or pins and needles
Numbness in an arm, hand, leg or foot
Muscle weakness in the affected limb
Difficulty bending or straightening the back
Sciatica occurs when a lower back disc affects the nerve roots supplying the leg

Not all slipped discs cause symptoms. A person may have a herniated disc without experiencing pain, numbness or weakness.

Symptoms of Slip Disc That Should Not Be Ignored

Persistent or worsening pain, numbness or weakness may indicate ongoing irritation or compression of a spinal nerve. Symptoms of slip disc that begin to affect movement or everyday activities should be medically assessed.

The table below highlights slipped disc symptoms that should not be ignored:

Symptom	What It May Indicate
Persistent back or neck pain that is not improving	An ongoing spinal or disc problem that requires assessment
Pain repeatedly spreading into an arm or leg	Irritation or compression of a spinal nerve root
Persistent tingling or pins and needles	Sensory nerve irritation or compression
Persistent numbness in an arm, hand, leg or foot	Reduced nerve function affecting sensation
New or worsening muscle weakness	Increasing compression or impairment of a motor nerve
Increasing difficulty walking or using an arm or hand	More significant neurological involvement
Pain or neurological symptoms affecting normal activities	Persistent nerve-related symptoms that may require further assessment

Pain, numbness and weakness are particularly associated with a herniated disc when displaced disc material irritates or compresses a nearby nerve.

Why Do Slip Disc Symptoms Occur?

Slip disc symptoms usually occur when part of an intervertebral disc bulges or herniates and irritates or compresses a nearby spinal nerve. This can cause local back or neck pain and pain that travels along the affected nerve into an arm or leg.

Pressure or inflammation around sensory nerves can cause tingling, pins and needles or numbness, while involvement of motor nerves can lead to muscle weakness. Symptoms may become worse during certain movements, coughing or sneezing because these actions can increase irritation around an affected nerve.

The location of the disc determines where symptoms are felt. For example, lumbar discs commonly affect the buttocks and legs, while cervical discs may affect the shoulders, arms and hands.

Symptoms That Require Immediate Medical Attention

Rarely, a slipped disc can severely compress the nerves at the lower end of the spinal canal and cause cauda equina syndrome. This requires immediate medical assessment because delayed treatment can result in permanent neurological problems.

Seek emergency medical attention for:

New numbness or loss of sensation around the genitals, anus, buttocks or inner thighs
New difficulty starting urination or being unable to pass urine
New loss of bladder control
New loss of bowel control or reduced sensation when passing stool
New or rapidly worsening weakness or numbness affecting both legs
New loss of sexual sensation or sexual function together with bladder, bowel or saddle-area symptoms
Severe back or leg symptoms accompanied by rapidly worsening difficulty walking

Back or neck symptoms that begin after a serious accident, such as a major road traffic collision, also need urgent medical assessment.

Symptoms of Slip Disc Based on Type

Slip disc symptoms differ according to which part of the spine is affected. The table below compares the main symptoms of different types of slip disc:

Type	Symptoms
Lumbar slipped disc	Lower back pain, sharp, burning or shooting pain from the buttock into the leg or foot, tingling, numbness or leg weakness
Cervical slipped disc	Neck or shoulder-blade pain, pain spreading into the shoulder, arm, hand or fingers, tingling, numbness or arm weakness
Thoracic slipped disc	Mid or upper-back pain that may spread around the rib cage or chest wall, band-like numbness or altered sensation may occur

Thoracic disc herniation is considerably less common than lumbar or cervical disc herniation.

Symptoms of Slip Disc-Specific Conditions

A herniated disc can irritate different nerve structures depending on its location. This can produce recognised nerve-related presentations. The following table summarises important slip disc associated conditions and their symptoms:

Condition	Symptoms
Sciatica or lumbar radiculopathy	Shooting, burning or electric-like pain from the buttock into one leg, sometimes with tingling, numbness or weakness
Cervical radiculopathy	Neck or shoulder pain spreading into the arm or hand, with possible tingling, numbness or weakness
Cauda equina syndrome	Saddle-area numbness, bladder or bowel disturbance, sexual dysfunction and new or worsening leg weakness or numbness

Cauda equina syndrome is a rare neurological emergency and needs immediate assessment.

Can You Have a Slip Disc Without Symptoms?

Yes. A slipped disc can exist without noticeable symptoms when it does not significantly irritate or compress nearby nerves. Some disc abnormalities are discovered incidentally during imaging performed for another reason.

An abnormal disc seen on a scan does not automatically mean that it is causing pain to the person. This is why doctors evaluate the symptoms, results of the physical examination and imaging findings together to determine whether a disc abnormality is causing the symptoms.

When Can Slip Disc Symptoms Become Life-Threatening?

A slipped disc is not usually life-threatening. However, certain symptoms can indicate severe compression of spinal nerves, particularly cauda equina syndrome, which is a neurological emergency, and a delayed treatment may cause permanent loss of function.

The table below shows symptoms that require emergency assessment and explains why they are serious:

Symptom	Why It Is Serious
Numbness around the genitals, anus, buttocks or inner thighs	May indicate compression of the cauda equina nerves that control sensation in the saddle area
Difficulty starting urination or inability to pass urine	May indicate impaired bladder nerve function caused by severe nerve compression
New loss of bladder or bowel control	May indicate cauda equina syndrome and can lead to permanent bladder or bowel dysfunction
New sexual dysfunction with saddle-area sensory changes	May indicate damage to nerves controlling genital sensation and sexual function
Rapidly worsening weakness or numbness in both legs	May indicate severe compression affecting multiple spinal nerve roots
Severe difficulty walking with worsening leg weakness	May indicate significant neurological impairment requiring urgent assessment

How are Slip Disc Symptoms Diagnosed?

Doctors diagnose a slipped disc by assessing the pattern of pain and neurological symptoms and performing a physical examination. Imaging is not routinely required for every person with back pain or sciatica and is generally considered when the findings could change management or a serious cause is suspected.

The following assessments and tests may be used to diagnose a slip disc:

Diagnostic Test or Assessment	Purpose
Medical history	Reviews the location, duration and pattern of pain, numbness, tingling and weakness
Physical examination	Assesses movement, pain and how symptoms affect normal function
Neurological examination	Checks muscle strength, sensation and reflexes for signs of nerve involvement
Straight leg raise test	Helps assess irritation of lumbar nerve roots in people with radiating leg pain
MRI scan	Shows discs, spinal nerves and the spinal canal when imaging is clinically required
CT scan	Provides cross-sectional images of the spine when additional imaging is needed or MRI is unsuitable
EMG or nerve conduction studies	May help determine which nerve or nerve root is affected in selected cases
X-ray	May identify some alternative bone-related causes of pain but cannot diagnose a herniated disc by itself

MRI is not required for every person with back pain or suspected slipped disc problems. A neurological examination may be performed to assess muscle strength, sensation and reflexes and determine whether nerve function is affected.

FAQs

Q1. What is the first symptom of a slipped disc?

Ans: A slipped disc commonly causes back or neck pain first. Pain may later spread into an arm or leg if a nearby nerve is affected.
Q2. Can a slipped disc develop without symptoms?

Ans: A slipped disc can cause no noticeable symptoms when it does not significantly irritate a nearby nerve.
Q3. Which slipped disc symptoms should never be ignored?

Ans: Loss of bladder or bowel control, severe weakness in the limbs and saddle numbness are symptoms of a slipped disc that should never be ignored and require immediate medical attention.
Q4. Are slipped disc symptoms different in men and women?

Ans: Slipped disc symptoms are generally similar in men and women. The pattern mainly depends on the location of the affected disc and nerve.
Q5. Can coughing or sneezing make slipped disc pain worse?

Ans: Slipped disc pain can become worse when coughing, sneezing or straining, particularly when a spinal nerve is irritated.
Q6. When should I see a doctor for slip disc symptoms?
