Brief Answer:
Baker's cyst?

Detailed Answer:

it sounds like Baker's cyst (popliteal cyst). This is a rather common condition which emerges as a result of various kinds of arthritis or knee injury or wear (like a torn meniscus for example). There are various approaches to such a cyst, including drainage, pain control and various conservative measures like rest, ice, elevation, etc.

The first thing to do is to get a diagnosis. You should visit your doctor for clinical examination. If your doctor is not certain about the diagnosis, an ultrasound scan can be ordered.

I hope you find my comments helpful!
You can contact me again, if you'd like any clarification or further information.
