How does sciatica lead to struggling with walking, and what can be done about it?

Sciatica affects the sciatic nerve, which extends from the lower back down each leg. When this nerve becomes compressed or irritated, it can cause pain, numbness, or weakness in the leg. Since the nerve controls leg muscles, these symptoms can make walking and maintaining balance difficult. People with sciatica often struggle with walking because their leg feels weak or their pain is worsened with bearing weight on their leg. If you're experiencing leg pain or difficulty walking, consider using a free symptom checker to better understand your symptoms before consulting with a healthcare provider. To address this, doctors typically recommend physical therapy that includes targeted exercises to stretch and strengthen the back and leg muscles. Pain relievers and anti-inflammatory medications can help manage discomfort and improve mobility. Sometimes, doctors may administer injections to reduce nerve inflammation. Simple lifestyle changes—like maintaining a healthy weight and practicing good posture—can also improve movement and decrease pressure on the nerve.
