My bone marrow biopsy was yesterday. Lidocaine did a fairly good job of dulling the drilling (a few seconds of level 5 pain while she was finding the sweet spot) drilling into the bone didn't hurt and the vibration was interesting. Now I have a compression bandage that covers much of my right upper butt. It will take about a week to see if I have SMM, MM, or likely AL amyloidosis. If I were to get a tattoo it would be a barcode with my 70 yo birthday as a use-by date (every day from then is a gift). Positive attitudes are tough to keep, but important.
