The Attempt at a Solution

Lymphatic edema is the collection of lymp fluid, this causes limbs to swell. Manual lymphatic drainage and compression garments are used to treat lymphatic edema. When the effected area such as the leg is massaged it causes the smooth muscle in the lyph vessel walls to contract opening the valves allowing lymph to drain. When compression bandages are used it casues the lymph vessels valves to be open allowing the lyph fluid to leak through reducing the swelling.
Couldn't find a explanation on how the treatment helped other than it helps move lymph fluid. So I applied it to the research I have done of the lymphatic system, so I am not sure it is correct.

Having been on the receiving end of these therapies, this sounds good to me, but that's from patient to therapist.

I would add elevating the effected part to get some help from gravity and active use of muscles as well as passive, muscle contractions compress the lymph ducts forcing the fluid through the valves, much like venous return from the legs.
You might want to mention management of the cause, inflammation, infections, tumors and trauma might all cause localized obstruction.
