Just to add my two cents worth,
I had three doses of cisplatin 1 every three weeks during my radiation. I have just had a follow up and because I complained of hearing problems I had a test. I have a slight loss at high end but nothing too serious. I also have developed peripheral neuropathy in my fingers and feet, I am waiting to see Oncology about this but it is thought to be a side effect of the cisplatin. It is a minor annoyance.
