I will answer the bone marrow test. First let me say I had MDS, and I was told the bone marrow is the truth teller about our blood. The only way to get that truth is to get a sample of the bone marrow and the bone. You can look it up. I will say i have had 4. Yesterday was my 4th. You lay flat on your tummy with your head on a pillow. They expose a spot on your hip. Your pants and undies are slid down a to get access to that spot, iliac crest on your hip. You are numbed with lidocaine first. I will say it has a weird feel. Not painful like a sharp pain, but they do have a different needle to extract each product, and it is a sensation or a pressure that lasts briefly, but for me was manageable. They will ask you throughout if you are ok. Tell the truth always. They may have solutions, like more numbing.
I had 2 friends say they were in the room as this was done on their loved ones. Let's say it is harder to watch then to get it. At the COH in Duarte and as I expect at other hospitals like mine, these teams do these all day. It takes less than 10 minutes to prep you and get it ready. 30 minutes from walk in till you leave.
I said yes to it, because it gave me answers to the blood numbers i was having. Three times I have had the same Physician's Assistant. She remembers me each time. She is calming.
