Have you heard of a Baker cyst? It’s a fluid-filled growth that can be found behind the knee, causing a noticeable bulge and tightness. Sometimes this type of cyst can also cause pain, worsening with activity or when you fully straighten or bend your knee.
Typically, a Baker cyst results from an underlying issue with the knee joint, such as arthritis or a cartilage tear. This can cause the knee to produce an excess amount of fluid. While a Baker cyst can be uncomfortable, treating the root cause of the issue can provide relief.
