Per UpToDate, the key here is the allodynia. This patient has intact sensation, it's just "turned up" way too much. The simplest way to explain this is that the sensor itself (the nociceptor) is over-activated.

Note that nociceptive pain (as this is termed) is more often due to inflammation/pressure/tissue damage, whereas neuropathic pain (more central) has a wide variety of causes (diabetes is a prominent one).
