It would hurt, then again, breaking a bone hurts too.
Yes, you can take it off when you are sleeping but wrap it up with something tight so it doesn't get worse.
The leg bone
There is no difference. A sprained ankle can also be known as an ankle sprain, twisted ankle, rolled ankle, ankle ligament injury, or ankle injury. It's when one or more ligaments are torn or partially torn where they are connected to your ankle bone.
The ankle is formed by three bones: the tibia, fibula, and talus.
Ankle bone
It depends on what bone you chipped because it can be very serious
Talus
Deep bone
A sprained ankle typically involves damage to the ligaments surrounding the ankle joint rather than a specific bone. However, in some cases, a sprained ankle can also involve a fracture in one of the ankle bones.
Arthroscopic
The medial ankle projection is on the tibia bone. But the medial ankle projection is actually called medial malleolus.
There are several bones in the Ankle. However, the one most commonly referred to as the "Ankle Bone" (the knob-like bone that protrudes out from where the ankle rotates) is called the Medial Malleolus.
