What is a popliteal nerve block?
A popliteal nerve block is a shot of numbing medicine that blocks pain from the lower leg. It's used for some procedures on the foot or ankle. It can also help reduce pain after a procedure.
The nerve block goes into the back of the knee, in the space called the popliteal fossa. It works by numbing the sciatic nerve, which runs down the back of the leg behind the knee.
