I Completed 6 Months Of Chemotherapy Followed By An Injection

I completed 6 months of chemotherapy followed by an injection of Neulasta after every treatment. I expected and dealt with the bone pain during chemo, because it is and my Oncologist agreed that it was the result of the Neulasta injections. I also had a month of radiation treatments following the chemotherapy also. Chemo was completed in November 2015 and radiation January 2016. I still suffer from bone pain daily and wondered how long does the Neulasta stay in your system ? Thank You Faith Montella
