Cancer is a no win situation and I'm sorry! I found that Blue Stuff with Emu Oil helped my father's back when he was dying. His back was hurting because he couldn't get up and out of bed and after a while it was severe. Nothing like pain from cancer of course, but I read about Emu Oil and got a sample of blue stuff from bluesprings.com to try - it worked to alleviate the pain. It does not help my daughter so I believe it is a blood chemistry issue.. Worth a try however since they send free samples. In the end unfortunately cancer is so painful not even morphine will help. Prayer sometimes does - My gramps prayed and told us his cancer pain was gone - Who knows... Best wishes to you and yours!
