If it turns out that you do have granulomatous mastitis, there is a "user group" devoted to that condition on this Web site, which could be a good source of information amd support for you.
To find it, wave your cursor over the word "forums," next to the MedHelp logo at the top of this page, and when the drop-down menu apperars, click on "user groups." Once you are taken to that page, type "granulomatus mastitis" in the search box, and it will take you to that user group's page.

If you have no confidence in your Dr. then I suggest that you find another; perhaps a Breast Specialist. If you do have Granulomatous Mastitis you should know that it is VERY difficult to treat and is usually a chronic condition. From what you have posted I seriously believe you should be seeing a Breast Specialist who can better deal with your problem. Take care .....
