question: I spent two weeks last month in the hospital where I found out that I have a rare lung disease. Two days ago I woke up with both legs very swollen and tight. Since then the left one has gone down but the right leg and foot remain swollen and tight and in some spots very tender. They gave me shots while in the hospital to prevent blood clots, so of course that s the first thing I think. Any information would be appreciated. Thank you. Leta Mott
