Hi Lee
Yes the bone pain is probably down to the injection to increase the white blood cell count. I found that it lasted for approx 2 weeks before it subsided and during that time every bone in my body hurt, including teeth, ears etc, so I asked my Onco if I could receive some form of pain relief, which he declined stating tha it wasn't necessary to have the injections as it is not a requirement. I have found my white blood cell count has remained at approx 18000 over my last 5 cycles and have not experienced that particular side effect again, although I have been experiencing others.
All the best
Roy
