Thanks for the info Norm and everyone.
Finally getting proper pain relief, in the form of Pregabalin + Zomorph + Amitriptyline. This combination seems to be working, and I can get back to normal life. Chemo delayed by 1 week, and blood tests show full recovery after 23 days, so would probably have been OK to go ahead as originally planned.
Better still, I'm scheduled for Radiotherapy to nuke the troublesome tumour that's wrecked my life for the last four weeks, so should be able to dump all the pain meds by the end of May.
Glad to hear you found the Cabazitaxel easier than the Docataxel - I had issues with it too, but I kinda expected it and just got on with managing the side effects one by one, although a couple are still with me - two years after I finshed the treatment (peripheral neurophathy and toe nails).
I asked about anything that could help me recover a bit faster in future cycles, but drew a blank there.
PSA continues to go up, and up...
1 April 893
13 April 980
20 April 1114
28 April 1240
Given up caring about this number now. Oncoligist says not to bother with it - she's just had a referal for some guy who appears perfectly healthy, but with PSA of 17,000. Go figure.
I can only wait and see how I respond to Cabazitaxel - I'm hopeful, even if it only manages to slow things down a bit.
Thanks again for the info everyone.
