Lack of movement: You might not be able to move your leg or foot because of sciatica. This can cause your foot to just hang limp despite you trying to move it. Inability to walk: All of the symptoms of sciatica can come together and make it difficult for you to walk.

What can you do for unbearable sciatica?

Alternating heat and ice therapy can provide immediate relief of sciatic nerve pain. Ice can help reduce inflammation, while heat encourages blood flow to the painful area (which speeds healing). Heat and ice may also help ease painful muscle spasms that often accompany sciatica.

Why does walking make my sciatica worse?

The way you walk and stand can affect the path of your sciatic nerve from your lower back to your foot. Incorrect walking patterns can cause misalignment, fatigue, and/or excessive stress on your lower back tissues, which can irritate or compress your sciatic nerve roots, causing sciatica.
