This will depend on the severity of the injury in the first place. Generally speaking, usually, within 2 weeks, most sprains and strains will begin to feel better. It is always recommended to avoid strenuous exercise and activity like running for a minimum of 8 weeks to help the injury continue to heal and limit the risk of further damage. If the sprain or strain is severe, it can take up to a few months to completely get back to normal. Visit our urgent care location today if you need medical attention.
