Bone marrow biopsy - Well that sucked

I'm still not sure why I had to be awake for this procedure because it sucked. Let me set the scene. First the objective of this exercise is to inject a needle inside an incision made right above my tush/fanny/butt and suck out a teaspoon of liquid marrow and then extract a 2 to 3 cm piece of bone. Then at the same time I had to lay on a bed on my side with my knees to my chest. Challenging for me, awkward for the doctor, but achievable. Drugs included a pill to help with the nausea and morphine to make me relax. Then a local anesthetic applied to the area where the procedure took place. I'm not sure what was worst, the pushing/pressure of the needle on my bone or the weird feeling of marrow leaving my body because of the odd void left behind. The piece of bone they yanked out was the easy part. Glad it is over. A day later, I'm a bit sore, but active. Looking forward to the results. As a side note, the reason why this procedure had to be done is that the marrow is the site of normal production of blood cells (white, red, platelets). This is the only place where they can see if the blood cells may be lacking or abnormal in the development, produced in excess, or replaced by cells normally foreign to the marrow, ie cancer. In other words it is at the core and will help with understanding the progress of treatment.
