    Dr. Rappazzo interacted with me as minimally as possible on the call. She joined a few minutes early and didn't say much. Quite frankly, the visit seemed to be a nuisance to her. This is an annual visit so not a burden in terms of her time and it is my only time to get any new information or developments concerning my condition. The call probably lasted around 8 minutes in total. I have not been sending her messages via MyChart or taking her time between the annual visits either.
