Have you ever had that bone pain from taking neupogen? I took 900 mg a day by injection for 11 days. I didn’t notice anything until about half way into it. I had a persistent headache. A few days later though, I had shooting pains in my back, ribs, sternum and hips. I have a prescription for Percocet to try to help. I’m hoping that I’ll be back to normal in a day or so.
