Lymphedema?

I had a BMX on October 30th of last year 6 nodes taken as well. I've gotten use to the numbness and was told to expect it. However, the last few weeks there has been pain involved too. Last night I went to the ER because it felt like someone was driving a spike through my right hand (Side the nodes were removed from). The right side is slightly more swollen and has a bluish tint to it with a blue line that runs down my wrist to the elbow on the inside of my forearm. But the main issue for me is the pain that cannot be controlled. Even now, typing is painful.
