From your latest information above it would seem that you are not a patient within the Mayo system. It has been my experience that within Mayo all reports are promptly posted to the patient portal and the doctors supporting my care are all integrated and up to date with the latest findings whatever they may be. When dealing with doctors from within different medical facilities you can expect some of the less than optimum information sharing and delays that you are experiencing. That just may be something that you will need to deal with due to your location. In regards to your anxiety level you do need to be patient and try to remain calm………when the pertinent information becomes available the doctors will present the facts and lay out what they feel is the best course of action for your condition. Having such a plan going forward will really help lower that anxiety.
Good luck!

Regarding various comments on posting of reports - yes Mayo is excellent about posting results as soon as they are available. But other places do it too. I have patient portals with two other clinics (large networks) and each posts test results immediately upon being done.
And one of my clinics links with Mayo so everything shows up on both sites immediately. The other one for some reason does not link to my Mayo portal which is something they choose to not do. So I have to go directly there.
The problem is with small groups of doctors. They do the minimum required by law. In one case the doctor ordered a CT scan by a local Radiology group. The Radiologist sent the report to my Specialist's group which posted it and I could see it. I expect the institution which did the PET scan sent it to the ordering doctor immediately and that should be posted on your doctor's patient portal. I expect these organizations to do what they are supposed to do.
