My left foot has been swollen for 4 days. what can i do to reduce the swelling? i am a 40 year female who is overweight and am inactive. i stood on my feet the last several days cooking. i have a heart condition too.

If : If only one foot is swollen, it's unlikely it's from fluid retention or your heart. It's probably something local. It's hard to say exactly what is causing your swelling, although varicose veins and/or phlebitis come to mind. You're best off having your primary care physician take a look, especially given that you have a heart condition as well.
