Hi Margaret, the most common ways to manage symptoms are exercise and elevation of the limb, massage, and pneumatic compression or compression stockings. I can’t personally vouch for the effectiveness of a system such as Lympha Press, however there is evidence such compression devices may help with lymphedema. I understand the point your therapist may be making however in that there are many of these devices on the market, and not all are developed with lymphedema in mind. There is actually a clinical studies section on the Lympha Press website if you wish to do more reading around this type of treatment.
