I am a 70 yr. old women who has arthritic knees. I am in good physical condition and attend low impact exercise classes and weight bearing classes at our YMCA. I am also a walker. I developed a Baker's cyst behind my left knee and have been icing and elevating and using a dyclofenc gel for pain relief. My question, is my orthopedic said the cyst is small and will eventually go away. There are days when I feel great and days, after exercising, that my knee becomes stiff and sore... is this normal and does the Baker's cyst eventually disappear?
