Edema
"I have a genetic condition called Venous Insufficiency, which doesn&#039;t allow the blood &amp; fluid to be returned from my lower legs &amp; feet, so they swell and the skin can start to break down, which opens up the opportunity for infection.  Have been taking Furosemide 40mg 1x day for over a year now - it is the only thing that keeps me from being in the hospital all the time with infections that require IV antibiotics. The only side effects I&#039;ve noticed are the very frequent urination (not really a side effect, it&#039;s what the drug is *supposed* to do, as it flushes fluids out of the body), and aching in my legs and feet as the fluid leaves - I can only assume that is caused by my body trying to push the fluid out."
