I think you found an angel, and her name is Nikki. I never got to talk to Nikki until I was admitted to the hospital though the ER. Once she and Dr. Fujitani knew of my plight, they were so helpful and compassionate and they knew how much pain I was experiencing. They immediately took action to get me on track for surgery.
Dr. Fujitani can order whatever tests are needed to get the definitive diagnosis. Besides being a brilliant surgeon he is a really kind man, he will not be mad at you.
I don't know anything about the insurance situation, but if MALS is the suspected diagnosis and there is a chance of facetime with Dr. Fujitani, I would be doing a happy dance!!!
So, if it were me, I would just do everything Nikki told me to do. They saved my life!
