The prognosis for nerve injuries depends on the severity and mechanism of injury. If the nerve has simply been compressed and had its blood supply cut off for a while, it recovers in hours to weeks. If there is a more severe injury, where some nerve fibers are actually killed or disrupted, complete recovery can take months-years, while the fibers die back and re-grow from the spinal cord at the rate of about a millimeter a day. If the nerve is severed, including its connective tissue sheath, surgical reattachment can be required. For your injury, I would bet heavily on the first category.
You can have the extent of injury assessed with nerve conduction studies and electromyography after a couple of weeks, if you enjoy electric shocks and needles. Earlier than that it's a waste of time because the changes don't show up in the muscles until then. However, nothing anyone can do is likely to alter your recovery.
