The symptoms you're having sound like part of the peroneal nerve
is irritated--either from swelling or from the fracture
. Most of these injuries are stretch or bruising injuries, called neurapraxias, that resolve with time, usually about 3 months. Occasionally, a nerve can be severed, but usually there is muscle weakness
to show the more severe injury.
In principle, fractures of the fibular shaft are left to heal without surgery. We can remove a large portion of the fibula as bone graft without significant adverse effects, so we know the mid-portion of the fibula does not provide structural stability. The closer to the knee, however, the more likely to affect the common peroneal nerve and the closer to the ankle, the more likely the fracture will affect ankle stability.
There are key ligaments that stabilize the ankle in the area known as the syndesmosis. These ligaments can take longer to heal than a fracture or lower ankle injury.
Talk to your treating physician about the location of the fractures relative to the important structures.
