Does anybody here have more info or has had fluid retention as such: my legs and knees especially are swollen. After several blood tests ruled out anything serious I am forcing myself to see a specialist in a lymphedema clinic to help flush out the excess. I am on Lasix which has helped but the swelling still present; all tests were positive, but something must be causing this, I saw 3 different docs at the same clinic all said fluid/edema present but was brief and sent me away with lasix, when I brought myself into the clinic the assistant there said its lymph nodes problem possibly from groin area, she knew right away just by looking at my legs/knees/ an injury to my legs several weeks ago possibly brought this on, I am now having anxiety attacks from this as its just not going away, I hope the clinic helps me soon. Thanks
