In the UK there is a treatment called Aromazone, available in Beauty salons and hospitals, Big leg length boot which inflate sequencially through ten chambers and thirty minutes treatment is equal to hours of hand massage. We have found it very effective in my salon. It was invented in the USA by a Dr and an engineer for a grandchild with severe Lymphedema, there are small versions suitable for arm treatments also.
The machines can be purchased for home use but may be rather expensive.Hope that helps, Wendy.
