Dear Joe
you are going through what will probably be the hardest part of your ordeal,...the waitng.Everyone here will probably say the same thing,take a deep breath,then another and try to calm down.
You have found a good place to get all your fears and questions down in writing and i think you will find this very helpful as everyone here has been where you are now either as a patient or a caregiver, so we all understand.

Keep posting and let us know your results as soon as you get them
