Its my experience that GPs or family doctors are scared as heck to deal with really sick people. And of course, they don't have the skills. I have had a very difficult time the last 10 years (last 4 of which have been filled with surgeries) getting someone to manage everything for me. I know it sucks, but you really have to try to take charge of it yourself. It seems that no matter what these docs rarely speak to each other and then when adverse things happen, they just try to throw the ball back and forth into each others court with no one helping you or solving your problem.
So I would suggest you try to find a good Gastroentinologist doctor in your area. GIs are generally more capable and spend more time dealing with post-surgical issues than colorectal surgeons. However, if you are having particular issues with your stoma, you might want to deal with an ostomy nurse from your colorectal surgeons office.
also Irene - you are not very far from the Cleveland Clinic. Their GIs and colorectal surgeons are some of the best in the nation.
good luck.
