You do need to give a damaged nerve time to see what kind of recovery can be made (see website under nerve injuries and recovery). If the nerve does not heal, you may be stuck with motor weakness that will not recover. Pain can be modified with medications and if chronic pain is not tolerable, a spinal cord stimulator can be considered. I would not jump into that treatment unless at least six months has passed possibly a year.
