A baker's cyst is caused by fluid leaking into a space in the back of your knee and it can affect the back of the knee and calf with a soft lump or fluid filled sac, and even pain and swelling. A baker's cyst is usually caused by an underlying condition of the knee, like arthritis or torn cartilage or other injury, which could have happened with your fall. They often times go away on thier own, but they can also keep coming back. If the cyst ruptures, it will cause pain and swelling in the knee and calf. They are usually not dangerous and usually do not require any treatment unless it is quite bothersome to you, in which case they could either drain the cyst or in particularly bad cases they can do a surgery to get rid of it forever. Many times though, they don't cause any problems and will eventually go away.

Thank you so so much for explaining to me what a bakers sist was/is!!!!! I now understand it so much clearer, than explained to me at the hospital, and it is very painful, especially when "one" is not able to lay them selves down for a day or 2 to take care of it.Thanks again, have a happy healthy day!
