I want to know the answer to the following question:
What happens when an anesthetic injection is directed into the nerves a limb stump?
All the background I'm provided with is that "Local anesthetic injections into the nerves or sensitive areas of the stump may relieve pain for days, weeks, or sometimes permanently, despite the drug wearing off in a matter of hours; and small injections of hypertonic saline into the soft tissue between vertebrae produces local pain that radiates into the phantom limb for ten minutes or so and may be followed by hours, weeks or even longer of partial or total relief from phantom pain.". Is that enough to answer the question?
Answer: yes
