Often prescribed by your doctor, compression stockings can help to alleviate leg swelling and assist with venous insufficiencies and lymphatic diseases. By applying pressure from the ankle up the leg, compression hosiery promotes blood flow up the leg as it can help to prevent blood from pooling. This mild to moderate squeeze can be used to target pain from varicose veins, help with post-surgery care, alleviate leg swelling during pregnancy, aid athletes during training, or to help prevent clotting issues, swelling, and aching, heavy legs.
