Checking your feet at home is one of the simplest habits that can help you catch a small problem before it becomes a bigger one. Diabetes can affect nerves or blood flow, but not everyone with diabetes develops neuropathy or reduced circulation. A short daily look at your feet helps you notice changes early, whether or not those complications apply to you. American Diabetes Association If you have noticed burning, tingling, or numbness, our page on diabetic neuropathy treatment explains the drug-free options Dr. Lazarus offers.
This guide explains what to look at, a simple daily routine, what to avoid doing at home, and which changes should not wait. It is general education, not individual medical advice.
Why Daily Foot Checks Matter
Reduced feeling can make a blister, cut, or pressure area harder to notice, while reduced blood flow can make some wounds slower to heal. These complications affect some people with diabetes, not everyone. Looking at your feet each day is a low-effort way to catch a small change while it is still small. CDC diabetic foot-care guidance
What to Look At
Skin
Look over the tops, soles, heels, and the spaces between your toes for cuts, blisters, redness, swelling, dry or cracked patches, calluses, corns, drainage, or peeling that could suggest a fungal change. The spaces between the toes are easy to miss and worth checking every time. American Diabetes Association
Nails
Check nail thickness, color, and shape, along with the skin right around each nail. A nail that is becoming thicker, discolored, or is pressing into the surrounding skin is worth watching. Not every nail change is caused by diabetes, but it is still worth a look.
Color and Temperature
Compare both feet side by side. Note any area that looks unusually pale, red, dark, or bluish, or that feels noticeably warmer or cooler than the rest of the foot or the other foot. A consistent color and temperature pattern from day to day is reassuring; a sudden change is not.
Numbness, Tingling, or Burning
Pay attention to whether your feet feel different than usual, including numbness, tingling, a burning sensation, or areas where touch feels duller than normal. These sensations can be easy to dismiss, but they are worth tracking over time rather than ignoring.
Foot Shape and Pressure Spots
Bunions, hammertoes, prominent bones, and other shape changes can concentrate pressure under or around the foot. Look for calluses forming in the same spot repeatedly, since that pattern often points to where a shoe or your gait is putting extra pressure. Check the inside of your shoes, too, for a worn lining, a folded seam, or anything that could be creating friction. American Diabetes Association
A Simple Daily Routine
- Pick a consistent time, such as after a shower or before bed, so the habit is easy to keep.
- Sit down in good light and look at the top of each foot, then the sole, heel, and between each toe.
- Use a hand mirror, a mirror placed on the floor, or ask someone you trust to check the soles if you cannot see them easily.
- Run a hand gently over each foot to feel for warm spots, rough patches, or swelling you may not have noticed by sight alone.
- Check the inside of the shoes you are about to wear for anything that could rub or press against your skin.
- Note anything new. A quick phone photo can help you track whether a spot is changing over the following day or two.
Reduced sensation can make a problem less noticeable by feel, which is exactly why the visual check matters. CDC diabetic foot-care guidance
What to Avoid at Home
Do not cut into a painful nail, corn, or callus yourself, especially if you have reduced sensation, poor circulation, or another reason your feet are at higher risk. The ADA advises against self-treating ingrown nails and calluses in at-risk feet, and the CDC warns against removing corns or calluses with sharp tools or over-the-counter acid products. American Diabetes Association CDC diabetic foot-care guidance
Do not use very hot water or a heating pad on feet with reduced sensation. A temperature that feels safe to your hand may still injure skin that cannot sense heat normally. Avoid walking barefoot, including at home, since reduced sensation can let a small object go unnoticed.
Red Flags That Should Not Wait
Some changes need prompt medical attention rather than watchful waiting. Contact your primary care doctor or seek urgent medical care right away for:
- A new open sore, wound, or ulcer that has not healed within a day or two
- Redness that is spreading or getting larger
- Increasing warmth, swelling, or drainage around a sore or nail
- Fever along with any foot change
- A foot or toe turning dark, black, or blue
- Sudden, severe pain or a foot that becomes unusually cold
For a life-threatening emergency, call 911 or go to the nearest emergency department. American Diabetes Association
When Numbness, Tingling, or Burning Needs a Closer Look
Numbness, tingling, or a burning feeling in the feet can be signs that the nerves need attention, a condition known as neuropathy. Dr. Sean W. Lazarus, DPM, offers drug-free, non-surgical neuropathy care focused on supporting nerve function and comfort.

Frequently Asked Questions
How often should I check my feet if I have diabetes?
A daily check is a good habit. Picking a consistent time, such as after a shower, makes it easier to keep up with.
What should I look for during a home foot check?
Look at the skin, nails, color, and temperature of both feet, and note any numbness, tingling, burning, new pressure spots, or calluses. Checking between the toes and the soles matters as much as the parts you see easily.
Why do numbness, tingling, or burning in my feet matter?
These sensations can be signs that the nerves in your feet need attention. They are worth tracking and discussing with a clinician rather than dismissing as ordinary tiredness.
What should I do if I find a cut, blister, or sore?
Keep the area clean and protected, avoid walking on it more than necessary, and contact your primary care doctor promptly, especially since healing can be slower with diabetes. Do not try to treat it yourself if it is not clearly improving within a day or two.
Which foot changes need urgent medical care?
Spreading redness, increasing warmth or swelling, drainage, fever, a foot or toe turning dark or blue, or sudden severe pain all need prompt medical attention. Call 911 or go to the nearest emergency department for a life-threatening emergency.
