My Mom gets this shot as well. Sometimes she has nagging pain and sometimes it is excruciating. You are taking the shot to "rev up" the bone marrow production of white cells and therefore you do get bone pain.
My Mom sometimes does well with Advil, but there are Percocet times as well.
Hope you find what you need to keep the pain down. You have enough other things to worry about, right?
GOD bless you and give you peace.
Beth
