Is having very ticklish feet normal?

One reason feet are ticklish is that they have more densely packed nerve receptors than most other places on the body. Upwards of 8,000 nerve endings can be found in your foot. This huge amount of nerves makes your feet more sensitive than other body parts, and more ticklish, too. Ticklish feet are usually a good indication of health, says Nirenberg. Non-ticklish feet can indicate problems with nerve receptors caused by illnesses such as diabetes mellitus, arthritis, certain vitamin deficiencies, or thyroid problems. Some people do indeed have an extreme tickle response known as Hypergargalesthesia. This condition is characterized by an intense sensitivity to tickling, leading to an overwhelming reaction to touch. Hypergargalesthesia is not yet fully understood by scientists. Each of your feet has around 7,000 nerve endings. The brain power needed to process all the sensory information from your feet uses more of your sensory cortex.
