We will be off to Calgary Thursday for my husbands PET scan. He recently had a bone marrow test also. They still can't seem to find what was causing his fevers. The good things are; so far all tests have come back normal, and the last Dr. he saw gave him some antibiotics...he has not had a fever since!! I wish they had given him the antibiotics 2 yrs. ago ! I'm hoping that they will be all he needs. Still not all the results from the bone marrow tests are in, some take several weeks to culture we are told. The worry diet is still working though... Thanks for all the prayers and for being there for us.
