The most common causes of sciatica are herniated or bulging discs pressing on the sciatic nerve, spinal stenosis, piriformis syndrome, muscle imbalances, postural issues, or prolonged sitting that irritates the lower back and nerve roots.

You may have a serious sciatica issue if you experience persistent radiating pain down the leg, numbness, tingling, weakness in the foot or leg, or if symptoms follow a fall, accident, or sudden onset.

You should see a physical therapist if sciatica pain lasts more than a few days, keeps recurring, worsens over time, or affects your ability to sit, stand, walk, or complete daily activities.

Recovery from sciatica can take anywhere from a couple of weeks to several months depending on the underlying cause, how severe the nerve irritation is, and how early you begin guided rehabilitation.

Yes, but it’s important to choose exercises that reduce nerve irritation and strengthen core and gluteal muscles. A physical therapist can guide you through safe movement patterns to avoid aggravating the nerve.

You can help prevent sciatica by improving your posture, strengthening your core and hips, avoiding prolonged sitting, lifting with proper technique, and staying active with regular stretching and movement.

Sciatica pain often recurs because the underlying causes—like poor posture, weak core muscles, improper movement habits, or incomplete rehab—haven’t been fully addressed. Physical therapy targets the root to prevent flare-ups long-term.
