If your doctor believes it's in your best interest to have a bone marrow, and you trust your doctor, then I would have it done. I had a bone marrow exam. 1 hour before I took a Xanax..I hardly felt a thing..I'm glad I had the exam since it left nothing to the imagination..You need to trust your doctor if not then get a second opinion. you should have a partnership with your doctor if you don't feel like you do then it's time for a change.
