MRI's are a huge does of chaotic emf. Not good. What country do you live in? The reason for your doctor's shyness with the mold issue is that lobbyist's have done a good job getting the medical community to turn a blind eye to mold. This came about from huge pressure by insurance companies that were being sued over toxic molds. As usual, corporations can change the laws in favor of big business and at the expense of people. It's not fair but then the entire system is rigged from top to bottom for corporations. At some point one realizes this fully and lives life accordingly.
As far as you go, get out of there as mold is very toxic and from a total load standpoint alone, this can drastically reduce success for the body's ability to heal itself.
One option is to find a good environmental doctor for support in these areas. Just say NO to medical mainstream.
