Answer 1

The sciatic nerve, arising from the sacral plexus and associated with the condition sciatica, is likely to have been irritated during a superior hypogastric plexus block causing paresthesia going down the leg to the foot.

Step-by-step explanation:

The nerve most likely to have been irritated during a superior hypogastric plexus block, where a patient reports a paresthesia going down her leg and into her foot, is the sciatic nerve. This nerve is a systemic nerve from the sacral plexus that is a combination of the tibial and fibular nerves and extends across the hip joint and gluteal region into the upper posterior leg. It is often associated with the painful condition known as sciatica, which can result from inflammation or compression of the sciatic nerve or any of the spinal nerves that contribute to it.
