Again, if there is anyone out there that has had the same or similiar treatment who would be willing to speak with my dad I would appreciate it. He was so relieved to know that others have felt the feeling of glass in there throat. One person described it as men slashing. This made him feel like hey I am not losing it. Again, I am sure someone could encourage my dad to continue on with this radiation. I can only do so much because, like he said, I don't know (nor do I want to) how it feels. By the way, he also take activan .5mg before undergoing radiation treatment. My e-mail is [email protected] thanks.
