Anyone have a diagnostic laproscopy (sp)?

I have been having some pain near my belly button area and no pain pills will help it.  I have seen my regular PCP, done numerous tests, and nothing has been found but the pain keeps coming back.  I called Dr. Jan and he wants to do a laproscopic procedure where he just goes in and looks around to see if he can find anything.  I am wondering if anyone has had this done?  If so, what was your experience with it?  I know there is something wrong because I haven't had any problems since surgery and this pain is out of the norm for me. Thanks, Michelle
