Hi Terry,
I had a daily injection of amifostine for all 37 of my rad treatments. They alternated the injection site between the left and right upper back hip / butt area. They injected the first shot in my stomach above my belt line but since I had / have very little fat to spare in that area they switched to the upper hip / butt area. It smarted and hurt some but I never really experienced any more naseau than what I got from the chemo. I received my shot 30 minutes before each rad treatment so my rad docs were also on a tight schedule to get me in on time. I'm 10 months post Tx and my saliva production is pretty good although I do get dry mouth and require drinking a lot of water when I eat. For me, I would hate to see what my saliva (or lack thereof) would be had I not had the amifostine. As you can see everyone is different but if you can tolerate the drug then I'd say go for it. I had the attitude that I had nothing to lose and, hopefully, saliva to gain.
Good luck going forward with your treatments. We're here to listen and offer any support you need.
Hugs, Nancy
