Young people need to understand they must prevent open sores. Excellent foot care is essential in making sure there are no ingrown toenails, that toe nails are cut straight across, making sure the skin between the toes is kept dry and very clean to prevent fungus from developing. When the lymphatic system is not functioning or malfunctioning, these things tend to occur more often. Another important aspect of treatment which is often overlooked is exercise and activity. Getting the calf muscles to act like a pump assists in the movement of lymph fluid.
Swimming is especially good because of the hydrostatic pressure of the water on the limb.
Riding a bicycle, using a trampoline or rebounder or doing step exercises are also good. There aren't that many registered manual lymph drainage specialists and in many of the places my clients live that isn't an option. MLD is unfortunately quite expensive as well and is not covered by public health care. If parents don't have private insurance programs, it may not be feasible. Ideally parents should be taught some MLD techniques to use at home.
