I am getting ready to go for my mapping appt later this week, and I have asked for Amifostine as part of the treatment and they said sure, we could do that. My only concern, is they say its kind of painful at the injection point that it burns. Is this true??? Also, can anyone tell me how confining the mask is gonna be??? IMRT coming, and I am slightly claustrophobic and needing to know I can handle it.
