Cording and lymphodema comes and goes with me and will probably be life long as I have had all the nodes cleared. At the start it was horrible and took a lot of self massaging to get it down but now its pretty good. The cord bit I massaged a bit harder and it was like popping bubble wrap and eventually it went down. Sometimes on a walk I feel the arm stiffening again so I hold it over my head for a bit and it settles. I think the key is not to let it get away with too much. Don't lift heavy things with it, and self massage a lot.
