If you fell out of the bed in an awkward position or were sleep walking, yes, you could. The odds are very unlikely, however.
yes. you can most definitely sprain your ankle when you are sleeping. you can stretch in your sleep and stretch the ligaments to much. this however would not swell that much or even swell at all, but it will bruise and it will hurt very bad! i suggest staying off it for 3-4 weeks. if you have to go to work or to school instead of going to the ER and them telling you to just walk it off, or going to the doctors and them telling you the same thing, or having to wait a week for an appointment, just borrow some crutches from a friend or buy some at a drugstore. the same with a brace. get one that will keep your ankle in place while walking around and also when asleep. go to a local drugstore. some are great and at a low price. sprains also do not show up in x-rays, so the hospital and doctors appointments might just be a waist of your time as well as the doctor's time too, and also a missed day of work or school that could have been avoided. hope this helps.
An ankle sprain
The most common type is the inversion ankle sprain, in which the ankle rolls over on the outside.
It is generally easier to sprain your ankle than to break it. A sprain is a stretching or tearing of the ligaments, while a break is a fracture in the bone. The recovery time and treatment for a sprain are typically less extensive than for a break.
You will sprain your ankle.
It's a sprain in the upper ligament of your ankle. These are usually much more painful and take longer to heal. (I had one about 2 months ago and they suck). The only good part is that with a high ankle sprain there is less of a chance of recurring problems as compared to a low ankle sprain aka. regular sprain.
Yes. The amount of swelling depends on several things, such as how bad the sprain is, how strong your ankle is, whether this is your first sprain, and how fast you get ice and compression on it.

Normal anatomyThe ankle joint connects the foot with the leg. The ankle joint allows the foot to move upward and downward and in an inward and outward motion. Muscles, tendons, and ligaments surround the ankle providing the stability the ankle joint needs for walking and running.Type I ankle sprainThe most common way the ankle can be injured is by an ankle sprain. When an ankle is sprained ligaments on the ankle are either stretched, partially torn or completely torn. The most common type of sprain is an inversion injury, where the foot is rotated inward. Ankle sprains can range from mild, to moderate, and severe. Type 1 ankle sprain is a mild sprain. It occurs when the ligaments have been stretched or torn minimally.Type II ankle sprainType II ankle sprain is a moderate level of sprain. It occurs when some of the fibers of the ligaments are torn completely.Type III ankle sprainType III ankle sprain is the most severe ankle sprain. It occurs when the entire ligament is torn and there is great instability of the ankle joint.Reviewed ByReview Date: 05/01/2011Linda J.
