This is easily explained. If the legs are too swollen, the stockings can be quite uncomfortable and even painful. But by using the 'Fit King Leg Air Massager' your legs got better which makes the stockings much more comfortable. In Germany by experienced vein and lymph specialists it is well known that the anti-edema therapy (with manual lymphatic drainage in lymphedema or with compression bandages in venous edema) is the first pillar in therapy. After this when the leg is at it's thinnest, then comes the second pillar which is wearing compression stockings to hold this success. The problem is often, that the stockings are given too early before the swelling (edema) has gone down enough. And there is another reason. Most people can't bandage a leg in the right way, not even doctors and nurses. So the patients get medical compression stockings from the very beginning. As I was in hospital because of my first deep vein thrombosis in my left leg after hernia surgery, they even couldn't bandage my leg on a ward for vascular surgery! They just didn't know how to do it.
