Absolutely agree that you should not seek any advice from within the same medical group/hospital.
I had serious issues with two orthopedists (one for foot, other for shoulder) at our medical group. I sought doctors OUTSIDE that group. I wanted no "collaboration" or corroboration by doctors who would not go against what a colleague has said or done. It was the best decision possible because both my foot/ankle and the shoulder/arm injuries were substantial and yet each of the orthopedists at my original medical group staunchly denied that I actually had the traumas that were later substantiated by the doctors from OUTSIDE the original practice. Bottom line: I got the medical attention that my injuries required, and although my foot/ankle still has nerve issues, my shoulder/arm is 98% pain free. Where the original foot orthopedist had REFUSED to order an MRI (claiming that he saw no need, even with the evident swelling, my Pain Level as high as 8, and the nerve conduction studies results), the NEW medical practice went on the record as stating that a year later I STILL had swelling and ordered additional MRIs, which supported his diagnosis of damages to the foot/ankle and nerve damage up the leg and to my shoulder joint and tendons.
Do yourself a favor and seeks recommendations for reputable doctors OUTSIDE your present medical group. Be prepared to possibly just leave that group altogether. That is what I have done, so that only my outstanding primary care physician is in the "old" group. Do what is best for YOU. Of course they are thinking that you will bring a case against them. But you need to get help for your pain first and foremost. And at least consider getting advice (as I did) from a law firm dealing with injuries. No cost if the suit is lost. Lawyers do not favor losing their client's rightful case. In my situation, the suit is against the facility wherein I had a horrific fall against a concrete floor. At this point, I am not doing anything about the original medical practice because I fear they will dismiss me and then I'll lose my outstanding primary. Yes, she is EXCELLENT, and documented EVERYTHING that was resulting from the fall so that my medical records are "evidence."
Best of luck to you. Remember: Think of what YOU need.
