need some advice-again!

It has been about 5 months since I have asked for advice and this board has always helped this husband(thanks).One more time.
My wife was triple positive july(2007).She did Hercetin (1 YR) Taxol,FEC, Bi Lateral Masectomy,15 lymph node removal,3 positive then radiation.Last herceptin was 9/11/08.We will always be able to remember.Anyway she is very active(teaches aoerbics) and in great shape.She woke upThursday morning with her left wrist to her hand swollen.The very first time we have experienced any swelling.She called the oncologist's office and talked to his nurse and they said keep it elavated and call back Monday if it is not any better.I thought i remembered reading on this board that if you experieced any lymphadema to get it worked on right away.I just arrived late Thursday night from a business trip and found all this out when i got home.I am up and waiting for her surgeon's office to open so i can call.Has anyone had swelling in only part of the arm(wrist and hand)?
