I really appreciate your comments and letting me and others know what the effects of radiation cause I have been having the shoulder pains Sharpe pains I have had three shoulder surgeries in the past and it seems that it's effecting old injuries, I'm wondering if there are any excercisees or stretching I should do to my neck as it feels hard and hot inflamed it looks swelled up like a bull frog ,and they did another pet scan my oncologist said it still shows active although the lymph nodes look better he said he didn't want to scare me that he thinks the scan was to soon and that my inflammation might be giving a false reading so he said they will wait till early July for another pet scan. I'll be reading all the info you put out and once again I thank you for what you are doing here it is so encouraging hereing from someone who's been through this and is giving real information of what you've been through and what might be expected it takes a caring person to do what you are doing I look forward to every post
