Nerve Compression analogy

How about a nerve compression analogy?   You can describe this as a car running over a garden hose in the driveway.  If the car is on the hose for a month it is very unlikely to return to its normal shape quickly.  If the car is on the hose for a day, the return of the shape occurs much more quickly.  So, if the nerve is compressed for a long period of time, the function will take longer to return.
