For Lymphedema following things can help.
1. Elevation of the legs specially during sleeping hours ( foot of the bed elevated 15 to 20 degrees can be achieved by placing pillows beneath the matress).
2. Use elastic compression stockings.
3. Massage towards the trunk everyday. Can do it by hands or massaging device. Pneumatic compression devices are available it's cheap you can buy it on Amazon.
4. Twice daily washing of affected parts with soap and water.
