I am a year and a half out of treatments, (10 weeks of Rad, 3 courses of Cisplatin) and am still feeling the effects. I have ringing but it is slight. I'm still fatigued but slooowly getting better. They have run all the tests and thyroid and testosterone are nomal. The only anomaly is low blood count so I am taking iron. As for chemo brain, I'm convinced that there was permanent damage. During treatment, I couldn't concentrate long enough to read a book and now I can do that but I have been very absent minded, freak easily, and can't multi-task at all.
