How long does it take for a sprained foot to heal can not be generalized, it needs to be judged in conjunction with the severity of the patient’s sprain. If the patient is only simple sprain, there is no fracture, it is mostly a grade 1 or 2 injury, the patient can be completely healed within 2-12 weeks after the injury, and the prognosis is good, generally will not leave sequelae. If the patient has a severe sprain and fracture, the sprain can generally heal in about 3 months for people in good health; however, if the patient is older and in poorer health, the patient’s recovery time may be relatively slower, and there may be sequelae if the treatment is not appropriate. Therefore, if the foot sprain is determined to be a simple soft tissue injury, and the symptoms can be tolerated, generally do not need to be overly nervous, if necessary, with the topical medication to reduce swelling and pain relief treatment can be. If the discomfort is more serious, or even intolerable, we need to suspect the possibility of fracture, and recommend that we go to the orthopaedic department of the hospital in time for professional treatment.
