What Lower Back Pain on One Side Could Mean
Summary:
- One-sided lower back pain may result from muscle strain, spinal joint problems or irritated nerves.
- Pain on the left or right does not necessarily indicate a different condition.
- Kidney problems can sometimes cause discomfort around your lower back.
- Persistent pain or symptoms that affect your legs may require medical assessment.
Experiencing lower back pain on one side can be puzzling, especially when you’re unsure what caused it. The discomfort may come and go, worsen with movement or interfere with everyday activities, making it difficult to know what to do next.
If you’re experiencing lower back pain, understanding the symptoms and possible causes can help you recognise when you need to seek medical attention.
Why Does Lower Back Pain Only Show Up on One Side?
Your lower back contains muscles, joints, discs and nerves that support movement. When one of these structures becomes irritated or injured, you may feel pain mainly on the affected side.
However, as you may not feel discomfort directly over the affected area, location alone cannot confirm the cause.
Common Causes of Lower Back Pain on One Side
Several conditions can affect your lower back, and each may produce different symptoms.
Muscle Strain
Heavy lifting, sudden twisting or unfamiliar exercise can strain your back muscles. You may notice tenderness, stiffness or discomfort when bending or changing positions.
Slipped Disc or Nerve Irritation
A slipped or herniated disc occurs when part of a spinal disc pushes outwards and may irritate a nearby nerve.
This can cause sciatica, where pain travels from your lower back into your buttock or leg. Tingling, numbness or weakness may also occur.
Spinal Joint Problems
The small joints connecting your spinal bones can become irritated or develop age-related changes. This may cause discomfort when standing, twisting or bending backwards.
Does Left vs Right Side Lower Back Pain Mean Different Things?
Left-sided and right-sided lower back pain often have similar causes. Your doctor will consider when the pain started, what makes it worse and whether you have other symptoms.
Can Lower Back Pain Come From Somewhere Other Than the Spine?
Not all lower back pain starts in your muscles or spine. Sometimes, discomfort in this area may be linked to a problem elsewhere in your body.
For example, kidney stones can cause severe pain in your side or back that spreads towards the groin. Kidney infections may also cause back or side pain, often with fever or urinary symptoms.
When Should You See a Doctor for One-Sided Lower Back Pain?
Arrange a medical assessment if your lower back pain:
- Lasts several weeks or keeps returning
- Worsens or interferes with daily activities
- Spreads into your buttock or leg
- Comes with persistent numbness, tingling or weakness
Seek emergency care for new bladder or bowel control problems, groin numbness or rapidly worsening leg weakness, which may indicate serious nerve compression. Severe back or side pain with fever or urinary symptoms also requires urgent attention.
For sudden or severe back pain symptoms, you can contact Spire Orthopaedic Centre’s acute care and emergency services.
What Are The Treatment Options for One-Sided Lower Back Pain?
Lower back pain treatment in Singapore depends on the underlying cause, symptom severity and how the pain affects your daily activities.
Non-Surgical Treatment
Many cases can be managed without surgery. Depending on your condition, treatment may include:
- Activity adjustments: Reduce movements that worsen your pain while remaining gently active.
- Medication: Suitable pain relief or anti-inflammatory medication, where appropriate.
- Physiotherapy: Targeted exercises may help improve movement, strength and function.
When Is Further Treatment Needed?
If your lower back pain does not improve with initial treatment, your doctor may recommend further investigations to identify the underlying cause. This may include a magnetic resonance imaging (MRI) scan to check for nerve compression or other spinal problems.
Depending on the findings and your response to non-surgical treatment, your specialist may discuss treatment options such as:
- Epidural steroid injections: Medication is injected around the affected spinal nerves to reduce inflammation and pain.
- Discectomy: Surgery to remove part of a herniated disc that is pressing on a nerve.
- Laminectomy: A procedure that creates more space around compressed spinal nerves by removing part of the spinal bone.
- Spinal fusion: Surgery to join two or more spinal bones to improve stability in selected cases.
