Varies : There is not a set limit. Every time you do drain it, there is risk of introducing infection. Three times is a general rule. The bigger wuestion is why it keeps occurring and what can be done. A detailed exam and appropriate studies can determine the cause and options for treatment.

I have a bursa sac that filled during high school. It has led to no issues, other than being a huge sac to the left of my knee, and below it. Is there a health concern given that it has always been filled for 14 years? Should I get it drained?
