What Are The Causes Of Sciatica?
Sciatica can come from many different factors, ranging from external nerve irritation to direct compression within the spine. Different conditions can cause irritation, pinching, or compression to the sciatic nerve:
Herniated Disc (Slipped Disc)
When the soft center of a spinal disc pushes through the tough exterior, pressing directly on the sciatic nerve root.
A general narrowing of the spinal canal, which reduces the space for the spinal cord and nerves.
Spondylolisthesis
A condition where one vertebra slips forward over the one below it, pinching the nerve.
Trauma
Direct injury to the spine or pelvis that damages or compresses the nerve.
Pregnancy
The growing uterus and hormonal changes can put pressure on the sciatic nerve.
A person is at greater risk of developing sciatica if they are overweight, smoke, lead a sedentary lifestyle, have had a recent back or spinal injury, or suffer from conditions such as diabetes or osteoarthritis, all of which can increase pressure on or irritation of the sciatic nerve.
What Are The Types Of Sciatica?
Sciatica is categorized by the source of the nerve issue:
What Are The Symptoms Of Sciatica?
Sciatica symptoms can range from mild discomfort to severe, daily limitations. If your pain persists, worsens, or restricts your ability to perform simple actions, it's best to have it assessed by a specialist.
- Pain: Moderate to severe pain in the lower back, buttocks, and leg. May worsen with movement.
- Numbness or Weakness: May occur in the lower back, buttocks, leg, or feet.
- Other symptoms: Other symptoms include incontinence and paraesthesia (pins and needles) in their legs, toes or feet.
What Are The Treatment Options For Sciatica in Singapore?
Conservative Treatments
If your sciatica is mild, you will benefit from conservative treatments, including:
- Pharmacotherapy: Includes NSAIDs, muscle relaxants, antidepressants, and anti-seizure medications to improve pain.
- Physical Rehabilitative Therapies: Physiotherapists can help alleviate pain by using physical therapies to strengthen the supportive muscles and restore mobilirt and muscle function.
Minimally Invasive Procedures
If your nerve discomfort has been persistent or more severe, minimally invasive treatments can address the exact source without the need for open surgery. At Singapore Paincare, we offer precise procedures designed to relieve pain at its origin.
Surgical Options
Our specialist will discuss with you whether your sciatica requires surgery. Before recommending any surgical option, a specialist will review detailed scans of your spine to understand the exact cause. They will then discuss whether surgery is necessary and explain the potential benefits and risks. Generally, surgery may be recommended if your related causes of sciatica, such as a large herniated disc or severe spinal stenosis, require repair, or in severe, unresponsive cases.
- Microdiscectomy: A minimally invasive procedure to remove fragments from a herniated disk that are pressing on the nerve.
- Laminectomy: Removal of the lamina (part of the vertebral bone) that is causing pressure on the sciatic nerve.
How Can I Prevent Sciatica?
Some causes of sciatica may not be preventable. However, you can follow these tips to protect your back:
- Getting plenty of rest
- Exercising regularly
- Maintaining a good posture
- Maintaining a healthy weight
- Quit smoking
- Opt for low-impact activities such as swimming, walking, yoga or tai chi
A Message About Sciatica from Our Pain Specialist
Sciatica may start as a simple ache in the buttock or leg, but if ignored, it can affect how you move, sleep, and concentrate. Everyday factors like long hours of sitting, poor posture, spinal stenosis, muscle tightness, or pregnancy can trigger it. If left untreated, the nerve could become stiff, and pain, tingling, or weakness could spread down the entire leg.
Many people assume the issue is always a "slipped disc" requiring major surgery. In reality, tight muscles (Piriformis Syndrome), minor spinal narrowing (stenosis), or inflamed ligaments are often the real cause. That's why the first step is always to find out exactly where your pain comes from.
At Singapore Paincare, our Painostic® method goes beyond treating symptoms. We identify the real source of discomfort and build an individualized, minimally invasive plan—so you can move comfortably and confidently again.
