Depending on the severity of the injury, treatment for a sprain may require long rest or surgery, according to MedlinePlus. Avoid any physical activity that causes pain, apply ice to the wound for 20 minutes two to three times per day, keep the foot raised to help with swelling, and take prescribed pain medication as necessary.
Foot sprains can cause pain on multiple places across the foot, as well as bruising and swelling, and can make it impossible to put weight onto the foot, says MedlinePlus. A doctor may prescribe crutches, a splint or a cast to ensure that the foot does not sustain further injury during the healing process.
Treatment and care may take two to four weeks for minor sprains, while worse conditions may require six to eight weeks, according to MedlinePlus. If the injury is severe enough to require surgery, the healing process may take as long as six to eight months.
Attempt to resume light activity once the pain decreases, says MedlinePlus. It is important to pay attention to any pain that occurs. Wear stable and protective shoes to ensure adequate protection for the foot. If there is any sharp pain, stop the activity immediately, and if there is any discomfort, ice the area immediately after the activity.
