[|Human|] I have 3 painless moveable lumps beside my left knee cap. Started out as one but over the last two years it became three and now two are marble sized and one is oblong and about the size of a walnut. I also noticed that now below my Left knee there is a larger oblong area that protrudes noticeably...even more than on the Right leg. Very noticeable. No pain or tenderness. Is this a cause for concern or should I just keep an eye on it.
[|AI|]  Hi, Thank you for your query. I can understand your concerns. Painless movable lump around your left knee could be either Meniscal cyst or Sebaceous cyst or Bakers cyst. Meniscal cyst may result from trauma, hemorrhage, chronic infection, and mucoid degeneration. The most widely accepted theory describes meniscal cysts resulting from extrusion of synovial fluid through a peripherally extended horizontal meniscal tear, accumulating outside the joint capsule. They arise more commonly from the lateral joint margin, and occur most often in 20 to 40-year-old males. Sebaceous cysts originate from sebaceous glands in skin and contain sebum. Bakers cyst: A swelling or cyst at the back of the knee which is usually associated with rheumatoid arthritis. Regards
