It works by blocking a compound that supports the nerve cells involved in transmitting pain signals to the brain.
This doesn't say it just blocks the pain, it says it directly affects the nerve cells involved in transmitting pain. Those nerve cells could also be responsible for other unpleasant things, like generally complaining and always being inflamed and inhibiting proper healing.
