I was put under. I was also 13 so maybe they only do that for kids…

It truly depends on where you’re having the procedure and if you request it. I’ve been getting bone marrow biopsy since a child. During adolescence you will be put under. As an adult some physicians find it necessary to use local anesthesia or lidocaine to numb the area. Ironically, I am expecting to have another in 5weeks and I am being sedated. Not completely under. It will be my first time particularly awake for this procedure so please pray for me. I was told it will be painless or I may feel some movement but not a lot so idk.. but request it from your doctor and see what happens.
