Understanding sciatica: What is it and what should you look for?
Sciatica is a term used to describe pain that radiates along the path of the sciatic nerve, which extends from the lower back through the hips and down each leg. This condition often arises due to a herniated disc, where the cushioning discs between the vertebrae bulge and compress the sciatic nerve.
Herniated disc and sciatica symptoms
The most common symptoms of a herniated disc causing sciatica include pain that originates in the lower back and travels down the leg, numbness or tingling in the leg or foot, and muscle weakness that affects mobility. Recognizing these symptoms early is crucial for timely treatment.
How to tell if your lower back pain is sciatica?
Determining whether your lower back pain is sciatica involves looking at additional symptoms. If the pain radiates down one leg, particularly below the knee, it may indicate sciatica rather than a general back issue.
If you experience leg pain alongside lower back discomfort, it's essential to consult a healthcare professional. Diagnosis often involves a physical examination and may include imaging tests like an MRI to confirm whether sciatica is the cause.
Pinched nerve vs sciatica
While both conditions can cause similar symptoms, a pinched nerve is a broader term that refers to any nerve that is compressed, whereas sciatica specifically involves the sciatic nerve. Understanding this difference is vital for receiving the correct treatment.
Early signs of sciatica
Recognizing early signs of sciatica can lead to more effective treatment. If you notice pain that worsens with sitting, or discomfort that radiates down the leg, you should consider consulting a healthcare professional. Treatment options may include physical therapy, pain relief medications, and lifestyle adjustments.
Severe sciatica: when to seek medical help?
It's essential to seek medical assistance if you experience severe, persistent pain that does not improve with rest, increasing weakness in the leg, or loss of bladder or bowel control. These symptoms can indicate a more serious condition requiring immediate intervention.
Understanding chronic sciatica
Chronic sciatica typically lasts for more than three months. The long-term impact can include persistent pain, mobility limitations, and potential nerve damage.
Can sciatica cause permanent nerve damage?
Untreated sciatica can lead to permanent nerve damage. Signs to watch for include worsening numbness, muscle weakness, and loss of bladder or bowel control. Recognising these symptoms early is critical for preventing long-term effects.
Sciatica diagnosis: what tests will you need
In addition to MRIs, other diagnostic tests may include X-rays to check for structural problems, EMG (electromyography) to assess nerve function, and sciatic nerve function tests to evaluate the health of the nerve. This is determined individually, and prior discussion with your healthcare provider would be needed.
CT scan vs MRI for diagnosing sciatica
Both CT scans and MRIs can be useful in diagnosing sciatica. However, MRIs are generally preferred for evaluating soft tissues like discs and nerves, while CT scans may be more effective for assessing bone structures.
Which MRI scan is recommended for sciatica?
An MRI scan is a common diagnostic tool used to confirm the presence of sciatica. During the scan, detailed images of the spine are taken, which can identify herniated discs or other spinal issues pressing on the sciatic nerve.
For sciatica pain, a lumbar spine MRI is typically recommended. This imaging test provides detailed information about the structures in the lower back, including:
- Intervertebral discs - to identify herniation or bulging.
- Nerve roots - to detect compression or inflammation.
- Spinal canal - to assess for stenosis (narrowing).
- Soft tissues - to evaluate surrounding ligaments and muscles.
Does an MRI show nerve damage in sciatica patients?
An MRI can reveal structural problems that may be contributing to sciatica symptoms, but it does not directly show nerve damage. Instead, it helps doctors assess the underlying issues causing the pain.
When distinguishing between a pinched nerve and sciatica, MRI results can provide essential insights. The scan can pinpoint the location and cause of nerve compression, helping doctors determine the best course of action.
What to expect from a sciatic nerve function test
During a sciatic nerve function test, your doctor will evaluate muscle responses and nerve conduction to determine the extent of any nerve damage or dysfunction.
Effective sciatica pain relief options available in the UK
There are several effective pain relief options for sciatica in the UK, including physical therapy to strengthen muscles and improve flexibility, medications such as anti-inflammatories and muscle relaxants, and alternative therapies like acupuncture or massage.
For chronic cases, treatment may involve a multidisciplinary approach, combining physical therapy, medication, and possibly surgical options for severe cases.
How to relieve sciatica pain at home?
If you’re looking for ways to manage sciatica pain at home, consider gentle stretching exercises to relieve pressure on the nerve, applying heat or ice to reduce inflammation, and maintaining good posture when sitting or standing.
Treatment for Sciatica
See your doctor to confirm the diagnosis and discuss the best treatment plan for your symptoms. This could include:
- Self-Care
- Rest, but avoid prolonged sitting or lying down. Gentle movement promotes recovery.
- Use ice packs for the first 48 hours (15–20 minutes every 2 hours), then switch to heat for muscle relaxation.
- Gentle stretching and exercises, like yoga or walking, can help relieve tension in the back, hips, and legs.
- Medications
- Over-the-counter pain relief, like ibuprofen or paracetamol, can help reduce discomfort.
- Muscle relaxants may be prescribed for spasms.
- Medications for nerve pain, such as amitriptyline or gabapentin, can be helpful in more severe cases.
- Physical Therapy
- A physiotherapist can design exercises to strengthen your core, improve flexibility, and reduce nerve pressure.
- Lifestyle Adjustments
- Maintain good posture while sitting and standing.
- Manage weight to reduce pressure on the spine.
- Incorporate regular activity and avoid sitting for long hours.
- Medical Treatments
- Steroid injections may be offered to reduce inflammation around the affected nerve.
- Manual therapy, such as chiropractic adjustments, can improve mobility.
- Surgical Options
- Surgery is considered if sciatica persists for a long time or if there are severe symptoms like leg weakness or bladder issues.
- Common procedures include discectomy (removing part of a herniated disc) or laminectomy (removing bone causing nerve compression).
- Alternative Therapies
- Acupuncture and massage therapy can provide pain relief for some individuals.
- Mind-body techniques, like meditation, can help manage chronic pain.
Early intervention and a tailored approach can help most people recover without long-term issues.
Conclusion
Sciatica can significantly impact your quality of life, but recognizing the symptoms early and seeking appropriate treatment can lead to better outcomes. With various diagnostic tools available, including MRI and CT scans, healthcare professionals can determine the best course of action for relief. If you suspect you have sciatica, don't hesitate to seek medical advice to ensure you receive the care you need.

FAQs
1.When should you get an MRI for sciatica pain?
Consider getting an MRI if your symptoms persist despite conservative treatment.
2.Can an MRI detect sciatica-related nerve damage?
While an MRI helps identify structural causes of sciatica, it does not directly show nerve damage. However, it can highlight conditions that may lead to nerve injury if left untreated.
3.Lower back pain, sciatica, and MRI: key insights for diagnosis
Understanding the relationship between lower back pain and sciatica is critical. An MRI can provide key insights into the cause of the pain, helping healthcare professionals create an effective treatment plan.
4. Should I rest if I have sciatica?
It’s okay to rest briefly if your sciatica pain is severe, but prolonged bed rest is not recommended as it may worsen symptoms. Instead, focus on staying as active as possible with gentle movements like walking or stretching, which can help reduce inflammation and improve flexibility.
5. Can weight gain during pregnancy cause sciatica
Yes, weight gain during pregnancy can contribute to sciatica. The added weight increases pressure on the spine and pelvic area, potentially compressing the sciatic nerve. Hormonal changes that loosen ligaments in preparation for childbirth may also destabilize the spine, exacerbating nerve compression.

Frequently asked questions
Do I need a GP-referral?
No prior GP-referral is required. Booking with us includes a GP phone consultation and referral. Shortly after booking you will be contacted by a GP from our team who will discuss your scan and provide a referral.
How long is an MRI scan?
MRI scans generally take a bit longer than other types of scans. Individual scans take 10-30 minutes depending on the body part being scanned, overall it can take anywhere from 15 minutes to 90 minutes. You do have to lay very still for an MRI and if there is movement the scan may need to be repeated which can add some additional time.
What’s included in my booking?
With your GetScanned booking, you will receive:
- A pre-scan phone consultation with a member of our medical team.
- A referral for the scan.
- Scheduling of a private MRI scan at your preferred scanning centre.
- Access to your written report by a radiologist.
- Access to your scan images (online and downloadable).
How much is a private MRI scan?
A private MRI scan cost varies depending on the part of the body being scanned and the location the scan is performed. Generally, a private MRI scan in the UK starts at around £350, and includes the scheduling, scan itself and results.
What’s the difference between an open and closed MRI?
Closed MRI machines are the traditional and first type of MRI. They are used more frequently because they provide higher quality images, however they aren’t ideal for certain types of scan or when the patient has limited mobility. Open or wide-bore MRI machines don’t involve lying in a tight cylinder, instead they have wider openings with more space and are therefore considered better if you suffer from claustrophobia. A standing MRI or upright MRI is a new type of open MRI that allows the patient to be in various different positions, including weight bearing positions. If you would prefer an open MRI please filter by MRI type to find an open MRI near you, but please be aware it is only available at certain locations.
