How many times have you heard somebody say that they have a pinched nerve in their back or a trapped nerve giving them pain in their neck? The language and imagery of pinching somebody or trapping fingers ina door certainly creates a strong sense of fear and trepidation. Yet we know that nerves can be flattened and can even get a bit scruffy looking , a little like arthritic change in joints, without it having to hurt.
As an example reach for that cup of tea beside you. Bring it to your mouth. Then put it down. As you do this simple movement nerves like the median and ulnar nerve are bent and stretched without undue consequences. In fact, this mechanical action on the nerves is hugely beneficial. What we perceive as a pinching of the nerve is an increased sensitivity due to stresses and stimuli.
