A Baker's cyst, also known as a popliteal cyst, is a type of fluid collection behind the knee. [4] Often there are no symptoms. [2] If symptoms do occur these may include swelling and pain behind the knee, or knee stiffness. [1] If the cyst breaks open, pain may significantly increase with swelling of the calf. [1]
Additionally, knee pain might stem from your back or hips, even if you don’t feel pain there, and sitting for too long accentuates problems in these areas as well.
Pain and swelling or focal mass at the level of the joint. The pain may be related to a meniscal tear or distension of the knee capsule or both. The mass varies in consistency from soft/fluctuant to hard. Size is variable, and meniscal cysts are known to change in size with knee flexion/extension.

The pain is worse with acute knee impact. The pain can be reproduced by extending the knee against resistance, stressing the quadriceps, or striking the knee. Pain is initially mild and intermittent. In the acute phase, the pain is severe and continuous in nature. Impact of the affected area can be very painful.
Liposuction is another option if the lipoma is soft and has a small connective tissue component. Liposuction typically results in less scarring; however, with large lipomas, it may fail to remove the entire tumor, which can lead to regrowth. [29] New methods under development are supposed to remove the lipomas without scarring.
There may be a lump, with or without pain. [1] Pain may increase with the growth of the tumor and may be worse at night and at rest. [1] [3] A bone tumor might present with an unexplained broken bone; with little or no trauma. [2] Additional symptoms may include fatigue, fever, weight loss, anemia and nausea.
