Extreme sensitivity or hyperesthesia affecting the extremities, particularly the fingertips and toes.
From Greek 'akron' (extremity, peak) + 'oa' (possibly from 'oia' meaning condition), a medical term for heightened sensation in the outer parts of the body.
This medical term captures something about the fingertips and toes that's scientifically real—they have incredibly dense nerve endings, making them both our most sensitive touch detectors and often the first places to feel pain.
