How can fluid buildup from pinched (compressed) nerves affect you?

ANSWER

If nerve compression lasts a long time, a protective barrier around the nerve may break down. Fluid may build up, which may cause:

  • Swelling
  • Extra pressure
  • Scarring

The scarring may interfere with the nerve's function.
