This depends on the sensation being transmitted to the brain. Some nerves travel at hundreds of metres per second (A-delta fibres), others travel at only 2 m/s (C-fibres).
The distance to the brain will impact the time taken for the sensation to be delivered to the brain. But it’s usually imperceptible because the signals are so quick.
Nociception (noxious stimulus) carried by C-fibres, are integrated in the thalamus and modulated by pro and anti-nociceptive areas of the brain, which can delay your perception of pain.

Is delayed pain perception a problem for very tall people such as those with giganticism?

The difference between nerves that carry light touch and nerves that carry deep pain is pretty big. Remember stubbing your toe and waiting for the pain to arrive?
The difference between a short person and a tall person is not as big as that.

Robert Wadlow (tallest man ever) died from an infection on his foot when he couldn’t feel a brace cutting into his skin.

This is why when you whack your shin, rubbing the skin dulls the pain. It is also why mentholated muscle rubs, and TENS units work.
