Sciatica is a common condition that affects the sciatic nerve, which runs from your lower back through your hips and down each leg. It can range from a dull ache to sharp, shooting pain that makes it hard to sit, stand, or walk. For some people it comes on suddenly after lifting something heavy or twisting awkwardly. For others it develops gradually over time.
Sciatica can show up in different ways. You might feel sharp pain that shoots down one leg, burning or tingling sensations, numbness in your leg or foot, or weakness that makes it hard to move your leg normally. It can stay localized to your glutes and upper leg or radiate all the way down to your foot. The pain is usually worse on one side and can get worse when you sit, cough, or sneeze.
What Causes Sciatica?
Sciatica can come from a variety of sources:
-
Herniated or bulging discs that press on the sciatic nerve
-
Spinal stenosis or narrowing of the spinal canal
-
Piriformis syndrome, where the piriformis muscle compresses the nerve
-
Degenerative disc disease or arthritis in the spine
-
Muscle imbalances and poor movement patterns
-
Previous injuries that never fully resolved
-
Prolonged sitting or repetitive movements that irritate the nerve
Sometimes the cause is obvious, like after lifting something heavy or a sudden twisting motion. Other times it develops slowly without a clear trigger.
When Sciatica Becomes Chronic
Acute sciatica usually improves within a few weeks with rest and activity modification. But for some people, the pain doesn't go away. Chronic sciatica lasts longer than three months and can be more complex to manage. It may involve multiple contributing factors including nerve irritation, muscle weakness, movement dysfunction, and nervous system sensitivity. Chronic pain can also take a toll mentally and emotionally, affecting mood, energy, and quality of life.
When to Seek Help
You don't need to wait until the pain is unbearable to get help. If sciatica is limiting your daily activities, affecting your work, or preventing you from doing things you enjoy, it's worth getting assessed.
