Why isn't the wound beneath my foot painful?
Peripheral neuropathy causes the loss of protective sensation. This dulls the pain receptors of the foot, making it unable to feel something that is stepped on, like a splinter or tack, or something that is developing on the foot, such as a callus. Just because a wound is present without pain, it doesn't mean it is not serious. In fact, the opposite is true...it is a medical emergency. A non-healing ulcer has the potential to become infected, putting the limb at risk. If you see that an ulcer is developing, be sure to contact your Houston foot specialist immediately.
