Your fingertips are some of the most sensitive parts of your body, because they contain many more nerve endings as compared to other areas such as your elbows. They send information to your brain about whether something is hot or cold, sharp or smooth, soft or hard.

The body’s nervous system is split into two parts:
The peripheral nervous system relays information between the central nervous system, and the rest of the body.

Peripheral neuropathy in particular is often underdiagnosed because of a lack of awareness among both patients and doctors.
There are many causes of peripheral neuropathy. These include:
