I Have Had Increasing Pain After My Gallbladder Surgery 12

I have had increasing pain after my gallbladder surgery 12 years ago, doctors say it not a clip problem I say it is after all scans show nothing else is wrong. Doctor today said he never heard of any problems with the clip. how do you find out if there is a problem with the clip. Been to ER 3 times and a number of Doctors they can't find anything I only have Medicare I need help PLEASE AGE 68 female, other wise healthy no problems until Gallbladder surgery. Why don't Doctors care about their patience anymore, I have just been brushed off.
