Pregnant women with sprained feet can reduce swelling by applying cold or hot compresses, elevating the injured part and reducing activities. Cold compresses should be applied within 48 hours of a sprained foot, to promote the contraction of ruptured blood vessels at the site of local injury, to promote swelling and relieve pain, while hot compresses should be applied after 48 hours to promote blood circulation and accelerate the absorption of bruises. Keep the injured foot elevated, usually in a horizontal position and keep the foot above the level of the heart, using gravity to accelerate the return of venous blood. Pregnant women should try to avoid activities after the sprain to help promote the smooth repair of soft tissues, usually about three weeks of rest can be recovered. In severe cases, appropriate external fixation protection, such as elastic bandage, plaster support or ankle protection, can play a role in local immobilization and control the development of swelling. It should be noted that, during pregnancy, you should not take medication without authorization, if you need to use medication under the guidance of a physician.
