This is Doctor Shearing, Medical Director of Pain Management North.
We've spoken on these videos about a number of things that can cause low back pain or
pain that radiates down the leg, but sometimes patients come in and they have pain that really
doesn't start in the low back, it's pain that's confined to the leg itself, in fact, sometimes
it starts just below the knee and heads down to the foot. There are a number of things
that can cause this sort of pain, but one of them is called peroneal nerve entrapment.
We have a nerve that branches off the sciatic nerve, and then comes around the knee and
goes outside of the lateral aspect of the leg, and down to the foot. That's called the
peroneal nerve, and sometimes it can get stuck in a little tunnel and then that can cause
pain that is distributed down the leg. This is a category of what we call neuropathic
pain, meaning that the nerve itself is being irritated and causing the pain as opposed
to the pain at the end of the nerve. This kind of pain responds well to several of the
medications that we have discussed. For example the tricyclic antidepressants, medications
like the gabapentin and pregabalin.
Occasionally the pain persists and medications are not effective, in which case surgery is
a very reasonable option. But typically that's in the minority of cases and only if the pain
lasts more than four or five months. Typically if there's a problem making this diagnosis,
nerve conduction studies or EMG studies are required. This is not one of the more common
indications for pain management therapy that comes along, but we do see it from time to
time, and it is important to keep in mind. Particularly if your pain really doesn't go
into the thigh, but is just in the portion of the leg below the knee.
That's all for now, this is Doctor Shearing with Pain Management North.
