A wound or ulcer beneath the foot is frequently caused by peripheral neuropathy, a loss of feeling. While neuropathy is more frequent among diabetics, it can also occur in non-diabetics. The wound is not painful because the neuropathy causes the foot to be numb.
The loss of protective feeling is caused by peripheral neuropathy. This dulls the pain receptors in the foot, making it difficult to detect a splinter or tack that has been walked on, as well as anything growing on the foot, such as a callus. It’s important to remember that just because a wound isn’t painful doesn’t imply it’s not significant. In reality, it’s the polar opposite…it’s a medical emergency. A non-healing ulcer can become infected, placing the limb at risk of infection. If you notice that an ulcer is forming, make an appointment with your Houston foot doctor right away.
