I mirror David's comments. My Oncologist also warned me about the side effects going into the treatment, telling me that by the time it's caught (I notice it) it could be too late. Sure enough, it happened. Hearing aids help some but most of it is high pitch loss and ringing. Being fatigued or stressed seems to add to the ringing. The plus side, the treatment(s) did the job! It may not be for everyone but as mentioned earlier there must be a reason it's still widely used, success rate at what it does.
Best wishes,
Steve
