@beanglow I had one done, in Sept 2017. That dr routinely uses versed, however there was none given to me. It was a pain-free procedure for me. There is another one scheduled in 2 weeks, different dr, different facility. Their protocol is no sedation, and I do not expect any issues. You might experience some discomfort from the pressure bandage when you sit for the next 24 hrs, but not much else. Has your dr told you the reason for the bone marrow biopsy, and how long the results will take to get back to you? I hope you can see by these replies, that there may be unwarranted concern about pain.
