Foot Drop: Common Peroneal Nerve
Have you ever crossed your legs, only to find your leg tingling with a sensation of 'pins & needles?' Since the Common Peroneal nerve is relatively exposed, similar to the ‘funny bone' in your elbow, this is not unusual.
A nerve the thickness of a pen, the Common Peroneal Nerve crosses from behind your knee, around the outside of your knee, to enter the muscles of the outside of your leg. This nerve gets compressed between the white covering of the muscles and the underlying bone, the fibula. Many times this nerve becomes subtly compressed and goes unnoticed until you get foot drop.
This nerve is susceptible to compression and may cause symptoms like difficulty lifting up your foot or toes, so your foot drags. It may cause numbness or buzzing below your knee, or feel like your leg is going to "give out" on you. Depending on the severity of nerve compromise, several conservative and surgical treatment options exist.
