baker's cyst

a baker's cyst, also known as a popliteal cyst, is a pocket of joint fluid that forms a lump behind the knee. often a baker's cyst is painless, but occasionally this pocket of fluid can tear open and drain into the tissues of the lower leg, causing pain and swelling.

symptoms include:

  • swelling behind the knee that may increase when a person stands.
  • discomfort behind the knee and into the upper calf, especially when the knee is completely bent or straight.
