Hi all, I had my first bone marrow biopsy today. I was extremely anxious after reading lots on the Internet and watching one on you tube. I had gas and air and it really was not as bad as I thought it was going to be. Slightly painful a couple of times but a few deep breaths helped. My leg was aching afterwards but taking paracetamol for that. I just wanted to reassure anyone else who is about to have one.
