first side effects

The most common side effects of Neulasta are bone aches, flu like symptoms, and nausea/vomiting. At 24 hours after the injection I had only a slight headache. At +30 hours I noticed aches in my pelvis, which I expected because the pelvis is one of the biggest repositories of marrow. I've read that bone aches are common because the drug makes the marrow work harder. I noticed that when I got stressed my pelvis started throbbing and the throbbing aches went up my spine. Just a thought, maybe stem cells from marrow in the vertebrae would move directly into the spinal fluid. Friday morning Tylenol didn't help the ache so I had half a Percocet, which helped some. Saturday morning I started with a whole Percocet which made the ache almost unnoticeable. I want to try to get by on Tylenol because Percocet is a narcotic, so tomorrow it's back to Tylenol. It will probably be at least a couple of weeks before there is any increase in strength, maybe several weeks.
