Maureen, you had a special friend in Leah which comes across in the video so much so, that even the newsreader was emotional. I'm so sorry she passed, she looks like an amazing lady.
As to your back pain, my own experience earlier this year may help inspire you with some confidence I hope. I had the same persistant pain in the same area you do, the bone scan lit up, the mri was inconclusive and the pet/ct was negative! I did'nt know what to think and nor did my onc, it was too small to biopsy so had to wait two months to repeat the mri which thankfully was negative
Weird thing is, I did'nt even notice the pain again once I heard those words lol...
I really hope your own scan will show the same, soon after all this I developed a severe bout of sciatica so maybe that had something to do with the bone scan lighting up, I dont know but just glad it was'nt cancer.
My best wishes to you, I wont say dont be scared because I know you will, but know too that many of us have gone though this with a happy outcome and you may too!!!!
