Sciatica is a painful condition that causes the sciatic nerve to become inflamed, irritated or pinched. This nerve is the largest single nerve in humans. It affects the entire lower half of the body from your lower back to the bottom of your feet. Let’s look at the causes and at how to treat sciatica symptoms so you can get effective pain relief.
Causes of sciatica
Sciatic nerve pain radiates down through the lower back. It then goes into the leg and is sometimes expressed most intensely as a pain in the hip and/or knee.
People who develop sciatica may experience other conditions such as:
- radiculopathy (or pinched nerves)
- herniated disk
- narrowing of the spinal cord canal
- disc degeneration or degenerative disc disease
- disc slipping
- lumbar spinal stenosis
- bone spurs and fractures
- spine/pelvic injury or scar tissue
- muscle inflammation
- internal bleeding
- piriformis syndrome
- trauma that affects the lumbar or gluteal regions (e.g. car accident, etc)
- weak abdominal or thigh muscles that cause undue stress to the lower back
Sciatica symptoms 101
Sciatica symptoms vary from person to person and are based on the underlying cause of the condition. Many people feel temporary symptoms for a few hours to a few weeks while others may suffer chronically.
Additionally, some symptoms develop slowly and quietly over time. Some people with sciatica may not even realize the cause of the pain until it becomes severe enough to seek medical advice.
Symptoms of sciatica include:
- Pain is usually in one leg and may possibly include the buttock, hamstring, knee, calf, ankle and/or foot
- Both legs may be affected, but most occurrences only affect 1 leg
- Weakness is common in the knees and feet
- Difficulty in bending the lower joints, bending over and/or lifting heavy objects is also common
- Reflexes in the legs may be weak and/or abnormal
- Numbness, feelings described as pins and needles, burning sensations in the buttock and leg or throbbing/sharp pains in the hip, knee or ankle are likely to occur
- Pain is likely to increase and make it challenging to sit down or to stand up
- Pain may graduate in intensity while standing still (walking or moving may temporarily decrease the pain somewhat)
How to diagnose sciatica
When diagnosing sciatica, your doctor will perform a comprehensive exam. This will likely involve tests that check the alignment of your spine, the strength of your knees and your reflex, motion and extremity sensitivity.
Your doctor may use x-rays or other imaging tests to identify the cause of your condition. She may also use these tests to check for spinal disc abnormalities. Once your diagnosis is established, treatment can begin.

There is no cure for sciatica. However, there are many standard and alternative treatments to help reduce pain and accelerate healing.
How to treat sciatica symptoms
Sciatica has, in most cases, a way of healing itself. It’s different from other types of pain because of the bodies’ abilities to “reabsorb the disc material that is causing symptoms.” This means that keeping up with a consistent level of activity is crucial to managing – and reducing – the pain.
