I had virtually all left side nodes removed (they couldn't find a 'sentinel' and now 2.5 yrs later indications of lymphedema only in my left hand. They've prescribed a compression sleeve and glove for 10-12 hrs a day, but I don't see any improvement. I even think it might be making things worse as my hand looks a bit more swollen after wearing these. I read one study that did show improvement in the compression group over a year, but interestingly, 30% of those in the none compression group didn't deteriorate at all...
