Arthritis may also cause excess fluid to build up between joints and may ultimately cause the fluid to form a cyst on the foot. The symptoms of a ganglion foot cyst can vary depending on the individual. The cyst is typically circular with a firm texture that is slightly pliable when pressed.
What causes a Baker's cyst? A Baker's cyst is caused when excess joint fluid is pushed into one of the small sacs of tissue behind the knee. When this sac fills with fluid and bulges out, it is called a cyst. The excess fluid is usually caused by conditions such as rheumatoid arthritis or osteoarthritis that irritate the knee.
