An effective way to relieve pain after a foot sprain is to rest, place an ice pack on the sprain, compress the area and elevate the foot, explains Drugs.com. Patients with grade II or grade III sprains may require rehabilitation to restore the foot's functionality, explains the American Orthopaedic Foot and Ankle Society.
Doctors advise patients to rest and stay off the injured foot for at least 48 hours, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The patient may need crutches to move around. An ice pack may also be placed on the sprained area for 20 minutes at a time about four to eight times a day; however, it should be applied for more than 20 minutes each time in order to avoid frostbite. Use a cold pack, or fill a plastic bag with crushed ice, and wrap it in a towel.
Compression of the sprained foot may help to reduce swelling, notes NIAMS. The patient may use elastic wraps, splints or special boots to compress the area. Elevating the foot also helps to reduce the swelling. The doctor may prescribe acetaminophen or ibuprofen to relieve the pain and reduce the swelling, says Drugs.com.
