Have you talked to your docs about the swelling? If it is persisting, I would be concerned by fluid load on heart and circulatory system. Do compression stockings help? Have you tried elevation above heart level and ankle/foot pumps?
Yes, Kinesio taping can help lymphedema, but precise placement and tension need to be figured out by a trained therapist based on your specific situation. It is usually an adjunct treatment, used with other PT, exercise, massage, and possibly meds to moblize the fluid.
Let us know how you progress.
