My legs did greatly decrease post DS, they are actually pretty much "normal" sized legs now. I no longer have extra fluid in my legs but I do have a bit of permanent swelling in my lower left leg (it was the biggest part of my leg that was most effected by lymphedema) but otherwise they are pretty normal looking.
My feet use to swell badly as well, to the point where I could no longer wear shoes or barely walk.
I am happy to say that they have not gotten swollen since surgery. Also the severe sensitivity in my legs has gone away, they can still be a little tender (I know there is no cure for lymphedema).
Some-days I do notice my leg might appear a bit bigger but sometimes I think that's just my mind playing a trick on me due to my strong feel of my intense symptoms returning.
Besides that unstable mental outlook everything is going very well.
And I do too as well wish there was more people here, I know for a fact I was misdiagnosis/un-diagnosed for a very long time before I finally found out what was going on with me.
