Q. Does the bone marrow draw hurt?
A. Despite common belief, it is actually much less painful than most people think. In a recent Regenexx survey, 83% of patients reported that the bone marrow draw was much less painful than they anticipated and they would return for a repeat treatment without hesitation. In my own practice I use a smaller needle and cannula than is custom and in my estimation over 95% of patients I perform the bone marrow aspiration have the same report as the Regenexx study.
