Hi Dianne........Can you tell me a bit more about Progressive Radiation Disease? I have never heard of it before. Does it specifically envolve the nerves in and around the neck area? Do you have limited range of motion? Does physical thearpy help at all? I have never heard of this before. If it is a progressive disease what are the supposed end results? I'm quite sure I don't suffer from this, and hopefully I never will; however, I am curious about the disease since I've never heard of it.....or maybe I've had my head in the sand and just didn't want to hear about it. LOL Either way, could you share a bit more information on this. Thanks! Sincerely, Donna
