I have a chronic issue with lymphedema in my left leg. I watch my diet, especially salt, but I have found relief based on a hospital stay. The hospital used what is called a graduated Intermittent Pneumatic Compression Device. It is that small device that pumps air into limb-specific wraps to prevent blood clots. I wear it I my sleep whenever my leg starts to swell and it makes a huge difference. While they make compression devices for lymphedema, the are awkward and expensive. The device I use can be purchased at a fraction of the price and can treat lymphedema on any limb by purchasing the the correct wrap, also inexpensive by comparison. Hope this helps.
