To be fair, we are taught in med school to avoid giving patients results over the phone. We are taught to give patients results' face-to-face, so that we can clarify and answer questions. We don't want the patient to mis-interpret what we say, google, and freak out for five weeks. We've actually been taught in med school that's it's ethically irresponsible in most cases to give results over the phone if you can't meet with patient soon after to clarify questions.

So, he's just doing what he's been taught is the right thing to do. I understand you're frustrated (I would be too), but try to think of it this way -- it really is irresponsible of him to give you a diagnosis over the phone without explaining his reasoning behind the diagnosis. You should at least recognize that he is trying to do the responsible thing with you. Now, ideally, he would try to fit you in earlier for a quick appointment, but perhaps his schedule is too booked and that's not possible.

Just try to relax and wait the five weeks out. Then once he explains his diagnosis, you can google to your hearts content. But at least you will have his explanation to guide you in your research, so you don't veer off course and needlessly freak yourself out.

On the other hand, if you really feel like you can't wait the five weeks, you always have the option of requesting your medical records from his office. In that case, just call his secretary and tell her that you would like a copy of your medical records. I don't really recommend this route (reading medical records without your doctor there to explain things to you can be a scary experience), but it is your right to do this, if you wish.
