My journey sounds similar to Joy. The third hit of neulasta (mind you I was very grateful to be able to have the neulasta based on what it was meant for). The pain from waist down was incredible, quite overwhelming to the point where i could not walk as it felt i was walking on the bones of my feet (you know how many bones are in our feet - 26) Ouch and crunch. Curled up in bed the panedeine didnt touch the sides - hubby phoned my oncologist who left a script at the hospital pharmacy for him to go pick up some Endone. This seemed to do the trick.
All the very best
