Hello Projectwoman,
I use kinseo tape for my hand (I have tried many things!). I was trained how to do it along with bandaging etc. Apparently it does not work for everyone, but it certainly helped me. Essentially the tape works by slightly lifting and stretching the outer dermis to give the lymph greater movement (I am not a medic but that is my understanding). As someone else says, you apply it, leave it on for a few days, take it off andgive the skin a rest. My lymphodema is worst in the fingers and back of the hand so compression is not so effective, but you can apply pieces of tape along the back of the finger.
The LSN has information about it on its website. I think you are right to check it out and the practitioners details - its very commonly used for treating sports injuries but lymphodema would be more unusual and so you need someone with this type of experience (though think the LSN provide a list).
Good Luck! Rattles
