Apply a suitable moisturizer to dry areas of the feet, especially the heels and soles. Avoid applying moisturizer between the toes, where excess moisture can encourage fungal growth.
Wash your feet with lukewarm water and dry them carefully, including between the toes.
Avoid very hot water, harsh soaps, and aggressive scrubbing. Do not cut thickened skin or attempt to remove deep cracks with sharp instruments.
If cracks become deep, painful, red, swollen, or begin to drain fluid, seek medical advice promptly.
2. Numbness or Reduced Sensation in the Toes
Numbness is one of the most important symptoms to recognize in people who have diabetes.
Persistently elevated blood glucose can damage peripheral nerves, a condition known as diabetic peripheral neuropathy.
The nerves in the feet are often affected first because they are among the longest nerves in the body.
People may describe numbness as a loss of feeling, a sensation of wearing thick socks when barefoot, or an inability to feel the floor normally.
Some people notice that they cannot easily distinguish between hot and cold surfaces. Others may fail to feel small objects inside their shoes.
Why is numbness dangerous?
Pain normally alerts us to injuries. When sensation is reduced, a person may continue walking on a blister, cut, pressure injury, or foreign object without realizing that damage is occurring.
Repeated pressure can worsen the injury, particularly beneath the toes and the ball of the foot.
Over time, an unnoticed wound can become infected and, in severe cases, develop into a diabetic foot ulcer.
What should you do?
If you have diabetes and notice new or worsening numbness, arrange a medical evaluation.
A healthcare professional may assess sensation, circulation, reflexes, and the condition of the skin.
Do not walk barefoot, even indoors, if you have reduced foot sensation. Wear properly fitting footwear and inspect your feet every day.
Numbness that begins suddenly, particularly when accompanied by weakness, severe pain, or other neurological symptoms, requires urgent assessment because it may have causes other than diabetic neuropathy.
3. Tingling, Burning, or Pins-and-Needles Sensations
Not everyone with diabetic neuropathy experiences numbness. Some people develop unusual sensations instead.
These may include tingling, burning, prickling, electric-shock-like discomfort, or the feeling that tiny needles are touching the skin.
Symptoms often begin in the toes and may gradually extend upward through the feet and lower legs.
They can be more noticeable at night, sometimes interfering with sleep.
What causes these sensations?
High blood glucose can injure peripheral nerves and disrupt the signals they transmit between the feet and the brain.
Damaged nerves may send abnormal signals, creating sensations of burning or tingling even when there is no obvious injury.
However, these symptoms are not exclusive to diabetes. Vitamin deficiencies, nerve compression, alcohol-related nerve damage, certain medications, and other medical conditions can produce similar complaints.
When should you seek medical advice?
Persistent or recurring tingling deserves evaluation, particularly if you have diabetes, prediabetes, or other risk factors for metabolic disease.
A clinician may assess blood glucose, vitamin levels, medication history, circulation, and other possible causes.
Do not assume that burning feet automatically mean your blood sugar is dangerously high. The symptom requires context and, when appropriate, testing.
If the discomfort is accompanied by new weakness, rapidly progressing numbness, or difficulty walking, seek prompt medical assessment.
4. Wounds That Heal Slowly or Refuse to Heal
A wound that takes unusually long to heal is a significant warning sign in someone with diabetes.
High blood glucose can interfere with normal immune function and wound healing. Poor circulation may reduce the delivery of oxygen and nutrients needed for tissue repair.
When neuropathy is also present, the person may repeatedly injure the same area without noticing it.
This combination can allow a small wound to become a chronic ulcer.
What does a diabetic foot ulcer look like?
A diabetic foot ulcer may appear as an open sore, a crater-like area, a wound beneath a callus, or a damaged patch of skin that does not improve as expected.
Some ulcers are painful, but others cause little discomfort because sensation is reduced.
They commonly develop in areas exposed to repeated pressure, such as the ball of the foot, the heel, or the underside of the toes.
Why is early treatment important?
An untreated ulcer can become infected. In more serious cases, infection may extend into deeper tissues or bone.
Severe infections and inadequate blood supply can threaten the affected foot or limb.
