Question
Patient Inquiry: After the bone marrow biopsy, is the anesthesia still ineffective, leading to pain?
Answer
During the bone marrow biopsy procedure, anesthesia can only numb the skin, subcutaneous tissue, and periosteum. The bone marrow cavity itself cannot be anesthetized. Therefore, when extracting the bone marrow, a severe pain can be felt, akin to a piercing sensation. Please be mentally prepared.
