1 week ago I was washing my floor (on my knees no longer than 10 minutes). A few minutes later my knee felt tight and like I had a bruise. After looking at it, I noticed a golf size swelling on the top of my knee. When touched it felt like liquid in it. I went to the Dr. the next day and he said it was Bursitis and to watch for redness and hot feeling as that is a sign of infection. I have tried to ice it and rest whenever possible (not easy w/ 3 little ones). The swelling has subsided but the wierd thing is the bruising. I was bruised on my knee, but now it seems daily I have a new bruise and it's not directly on my knee. It seems to be moving up and down my leg. Is this something I should see my Dr. again for?
