The main things that patients with sciatica should avoid doing include sitting or lying down for long periods of time, and using hot water bottles for pain relief, as the skin could be scalded if the skin is numb.

Is there a specific sleeping that is recommended for patients with sciatica?

It is strongly advised that patients who have experienced or who are experiencing sciatica symptoms do not sleep on their stomach, as this causes the spine to become twisted.

The ideal sleeping position is on the back with a pillow placed behind the knees.

What underlying conditions could be causing sciatica?

However, an inability to control bladder and bowel movements is a serious cause for concern, and sciatica symptoms can certainly lead to or include a rare condition known, in medical terms, as cauda equina syndrome, which simply refers to uncontrolled bladder and /or movements of the bowel. Sciatica may also indicate urinary incontinence in some patients.
