If you’ve seen the headline “9 symptoms in your feet that are a sign that something is wrong,” it’s worth taking seriously—but none of these signs points to one specific disease. Foot changes can reflect nerve problems, poor circulation, diabetes, kidney disease, infection, or ordinary foot conditions.
9 foot symptoms worth paying attention to
-
Persistent numbness — can occur with peripheral neuropathy, including diabetes-related nerve damage. NIDDK
-
Burning or tingling — often described as pins-and-needles and can be a sign of nerve irritation or neuropathy. NIDDK
-
Unexplained foot pain — especially burning, shooting, or pain from light touch.
-
Swollen feet or ankles — can occur with fluid retention, including in more advanced kidney disease, although there are many other causes. NIDDK
-
Cold feet or a noticeable temperature difference — can sometimes indicate reduced circulation. NIDDK
-
Slow-healing cuts or sores — particularly important in people with diabetes because nerve damage and reduced blood flow can make wounds harder to heal. NIDDK
-
Changes in skin color or texture — unusual paleness, redness, shiny skin, or pigmentation changes can warrant assessment. NIDDK
-
Loss of hair on the feet or lower legs — may occur with circulation problems, although it isn’t diagnostic by itself. NIDDK
-
Changes in the shape of the foot or toes — particularly in someone with diabetes, where nerve damage can occasionally contribute to serious structural changes such as Charcot foot. NIDDK
One important point
Foot symptoms do not automatically mean diabetes or kidney disease. For example, numbness can have several causes, and swelling can result from heart, vein, medication, or other problems.
If you have diabetes, checking your feet every day for cuts, sores, redness, swelling, or blisters is especially important. NIDDK
Seek prompt medical attention for a rapidly swollen/red/hot foot, a deep or infected wound, blackening skin, severe unexplained pain, or a foot that suddenly becomes cold or pale.
