In brief: Yes

Spinal stenosis generally causes diffuse weakness in both lower extremities and get aggravated with activity.
Leaning forward as you would on a bike or sleeping in a fetal position flexes the spine and generally alleviates the pain from stenosis. You appear to have a one level disc herniation which would cause numbness, weakness, spasm in the muscles that are innervated by that nerve root.

In brief: Spinal stenosis

Spinal stenosis can cause pain in both legs and is usually worse with standing and walking and is relieved with sitting.
Since the nerves are pinched and the nerves are what inner ate the muscles when this happens you can have significant muscle weakness.

In brief: It is possible

One can get sciatica as a result of herniated disk typically on same side as disk bulge but stenosis can give bilateral symptoms.
