If : If only one foot or leg is swollen, it usually means there is a local problem (like lymphedema, varicose veins, thrombophlebitis, etc.). But in your case, since both feet and legs are swollen, it means you are retaining fluid for some reason. The four most common causes of fluid retention deal with the heart, lungs, liver and kidneys. When the tissues are swollen, it can cause hydrostatic pressure on the smaller nerves which can produce pain. pins and needles is a feeling typical of pain associated with nerves.
