The bone marrow biopsy performed a month ago took three needles of anesthesia, how come the pain at the location of the biopsy today is whether the anesthetic touched a local nerve or is there any other disease

It is impossible to touch a local nerve. The local anesthetic used for bone marrow biopsy is procaine, and the risk factor is very low. If you touch a nerve, it is estimated that you will be paralyzed at that time.

In the case of a postoperative infection, was the dressing covering the puncture site soaked postoperatively? Was it taken off after three days? If that's okay, it's your psychological problem.
