Hi, diagnosed with 2 torn hip labrums hip specialist/ surgeon says i need surgery, but what determines that i need it other than feeling pain?

Limited activities: The decision for surgery should based on how you are feeling, how the problem is affecting your life, what the treatment options are, and what the risk and benefits are. If the issue is causing you pain and limits your normal activities, you need to do something. If the potential benefits of doing something out way the risks for you, then lean toward that treatment option.
