These issues include the appearance of a wound, blister, or bruise that does not begin to heal after a few days, or if the skin becomes red, warm, or painful, which may indicate a potential infection. A doctor should also be consulted if a callus contains dry blood inside, which may be an early sign of an ulcer under the skin. If any foot infection turns black and has a foul odor, these are signs of gangrene and require urgent medical attention [\[1\]](). Corns and calluses are thickened areas of skin that form as a result of repeated pressure or friction [\[2\]](). For diabetic patients, these skin issues may develop into serious sores or infections due to nerve damage and poor blood flow, which are common complications of diabetes that can affect the feet [\[1\]](). ## Why is foot care important for diabetics? Diabetes can cause nerve damage, known as diabetic neuropathy, which reduces sensation in the feet. This means a diabetic patient may not feel a small stone inside their sock or a blister on their foot, which could lead to wounds and sores without them realizing it. Additionally, poor blood flow to the feet makes it difficult for wounds or infections to heal. In some cases, a bad infection may never heal, which can lead to gangrene and eventually amputation [\[1\]](). Therefore, any change in corns or calluses warrants a prompt medical evaluation to prevent serious complications. ## Signs that require an immediate visit to the doctor In addition to the signs mentioned above, there are other indicators that require a visit to the doctor without delay if you are a diabetic: if you notice any redness, warmth, swelling, or pain in the area of the corn or callus. Likewise, if there is any discharge from the affected area, this may indicate an infection. You should also pay attention to any change in the shape of the foot, such as Charcot foot, which begins with redness, warmth, and swelling, and can lead to changes in the bones of the foot and toes [\[1\]](). ## Home care and prevention Diabetic patients should check their feet daily for any problems such as wounds, sores, red spots, swelling, fluid-filled blisters, ingrown toenails, corns, calluses, plantar warts, or warm spots [\[1\]](). If corns or calluses are present, you should talk to a podiatrist about the best way to care for them. If the doctor permits, a pumice stone can be used to gently smooth them after bathing, rubbing in only one direction to avoid tearing the skin. You should not attempt to cut corns or use chemical products to remove them, as this can cause skin damage and infection \[1, 2\].

At least once a year, a comprehensive foot exam should be performed, including an assessment of sensation and pulses in the feet. If the patient suffers from changes in foot shape, loss of sensation in the feet, peripheral artery disease, or has previously suffered from foot ulcers or amputation, a comprehensive foot exam must be performed at every healthcare visit [\[1\]](). ## Medical references - [Diabetes & Foot Problems]() - [Corns and Calluses]() General health education; not a substitute for individualized clinical assessment.
