I can’t speak to your exact example, but some nerve wirings are just frankly a bit weird owing to slightly ambiguous biological origins. For example, pain in males’ testicles is often felt as being somewhere in the abdomen despite the testes being outside of the abdomen. This happens because male testicles and female ovaries share their origins as being inside the abdomen in the fetal stage of development.
