The Tramadol has been keeping me comfortable. No more whining in the night from pain.  But unfortunately rest does not seem to have helped.  The oncologist is now suggesting that it could be metastatic lesions on the lower spine.  She is reluctant to put me under a general anaesthetic and says that even if xrays confirm it is metastatic lesions it wouldn't change the treatment protocol.  I've now been switched from Tramadol (which makes me feel very dopey) to a half tablet of paracetamol/codeine for the pain (as well as Piroxicam and Amantadine).

In general I'm still very happy and alert but I am not keen to walk too far unless I'm on the scent of something really interesting. And if I do try to do too much I usually pay for it later that night and the next day. 

My pawparent is worried about fractures. Does anyone have any experience with metastatic disease in the spine or other bones?  

Mum decided not to go ahead with xrays because they wouldn't necessarily show anything anyway.  But good news. The pain in my lower spine / back leg is under control and I am much more mobile (although still not as much as I was  a couple of months ago).

The other good news is that after 1 month on metronomic Palladia two of my lung mets haven't grown at all and the third one has only grown a little bit. The oncologist was very pleased and mum is beside herself with relief.

Also, thank you Jerry for the link to Nikki The Rot.   The journeys of other Tripawds are both inspiring and heartbreaking.  We are late in getting active on this wonderful website because mum would break down too much as she read the stories of others.
