Hello INA.
I am sorry you were dropped without a warning, But I am also hoping that since you are going to an expert that Deals with SI, then you will hopefully get a better understanding on your SI and the other issues that you have at this time. Try to stay positive if possible, you will only know how you like the therapist and their therapies when you get there to see them for your appointment. Take care of yourself INA. Soidhonia
