Cindy, as far as the hearing loss, I had cisplatin as my chemo treatment and had permanent hearing loss. I was told that was common for cisplatin patients. The cisplatin causes the small hairs in the ear to harden and that is what damages the ability to hear. I have a constant buzz in my hearing and a loss of the high frequency range. This was measured by a hearing specialist and charted. So it is possible that Harry is having a hearing issue. I cannot comment on the other part of your post.
