The time it takes for a patient to recover from a sprain or strain will basically depend on the degree to which it is present, as well as the care or rest that the person takes. Bearing in mind that, in most cases, sprains are minor injuries, but for some sets, they may tend to get worse.
However, on average, most of these injuries, which are mild or moderate, may improve after 2 to 4 weeks, depending on the patient’s own condition. But, if a more severe sprain is triggered, people will need much longer to heal(up to 8 weeks). Taking into account that, if surgery is required, the rehabilitation process will be slower.
