I've had a Bakers cyst behind my right knee for over six years. The golf-ball size cyst has remained constant during this period except when it occasionally swells slightly, usually following leg exercises like walking, jogging, biking and plyometric jumping exercises. I've never done anything to treat it short of laying off leg workouts when my knee becomes too stiff and inflexible. Its never very painful, but can become extremely uncomfortable.

Will BFST still heal this longstanding Bakers cyst ?
