"Need for pain relief for bone marrow biopsy"

I had my first bone marrow biopsy at Winchester hospital 2 years ago. I was offered entonox if needed, but I declined. It was quite a difficult procedure as my bones are “like concrete” , and the Dr had great difficult trying to insert the needle. Eventually a Registrar was called, and she managed to complete the biopsy. During all this, I still didn’t need any pain relief - yes it was a bit uncomfortable, but certainly bearable.

Fast forward to a month ago when I went to Dewsbury hospital for another biopsy. Yet again, the Dr was having difficult getting into the hip bone, and the pain became excruciating, causing him to abort the procedure. I have to say the Dr was very empathetic and understanding, and suggested he would probably have to sedate me.

I have just had a message saying I have to go this week for another attempt, and to pick up a prescription for a light sedation at the hospital pharmacy.

I am now feeling very anxious that the sedation won’t be strong enough, and if that turns out to be the case I will refuse to have the biopsy. I have marginal zone lymphoma with an enlarged spleen so really I suppose it should be done.
