When a Baker's cyst bursts, synovial fluid begins to leak into the calf region, and multiple symptoms develop, states Medical News Today. These symptoms include inflammation and swelling, reddening of the calf and sharp, severe pains in the knee. Because similar symptoms occur when there is a blood clot in a vein, immediate medical attention is needed to confirm the cause of the rupture. If the Baker's cyst caused the tear, the body eventually reabsorbs the synovial fluid within four weeks, and physicians may prescribe painkillers for pain relief.

Although treatment for a Baker's cyst is generally not required, doctors may recommend treating a cyst that has become large and painful. Some treatments include draining the synovial fluid with a needle, taking a corticosteroid medication to relieve pain or getting physical therapy, according to Healthline. Doctors may also suggest surgical removal if the Baker's cyst causes damage to knee cartilage or limits a person's range of motion.
