If you don't like your dr and you feel like he isn't providing you with the appropriate treatment that fits YOU as a person, then you should of course switch doctors! Everyone is different and requires various levels of treatment and options. I, for example, would refuse surgery except as a very last resort. I also don't like being on very strong medicine and am working toward a more holistic approach to control my symptoms through my diet and lifestyle and supplements, etc etc. But there are other people who would prefer a more traditional/cutting edge medicine approach to their treatment and that is the wonderful thing about
where we live and the resources available to us - YOU HAVE THE OPTION SINCE IT'S YOUR BODY!! :) I would start looking for another dr TODAY, you sound like you need a new situation!
In what area do you live? Maybe there are people here who can help refer you to a good GI in your area.
