On an average, the recovery time for sprained foot may range between 1 to 2 weeks, depending on the severity of the injury. The healing time largely depends on how the precautionary measures that need to be taken to make sure that the injury is not aggravated, are followed. If proper care is not taken, there are significant chances that the sprain will result in some severe foot problem, such as chronic foot pain, which will be worse than the sprain.
