Your toes may be small, but they can give big clues about your overall health.
Here are some signs that your toes might be warning you about something serious
Changes in nail color

Discoloration in your toenails – like yellowing, white streaks, or odd patterns – can signal a number of health concerns.
For example, mostly white nails with a pink edge (Terry’s nails) may point to liver disease or diabetes, while half-white, half-reddish nails can indicate kidney problems.
Cold toes

Frequently cold toes may be a sign of poor blood circulation, which is often linked to conditions such as diabetes, heart disease, or autoimmune disorders like lupus.
Persistent coldness without clear cause warrants medical attention.
Changes in nail shape

Toenails that curve inward, flatten, or become club-shaped can be associated with issues such as anemia, thyroid disorders, or even serious lung conditions like cystic fibrosis or lung cancer. Always investigate abnormal nail shapes.
Swollen toes

Swelling in your toes might be due to circulatory or lymphatic problems, infections, injuries, or even conditions like gout and psoriasis.
Less serious causes include standing too long, poor footwear, or high salt intake.
Tingling or numbness

A tingling or burning sensation – or complete numbness – may signal peripheral neuropathy, especially in people with diabetes.
This nerve condition can result in weakness and even muscle spasms, making it vital to address early.
Dark vertical bands or spots

Dark streaks or spots under the nail can indicate anything from fungal infections to skin cancer like melanoma.
While some bands are harmless (e.g., from hormone shifts or nail polish), persistent or spreading dark areas should be examined by a doctor.
Fungal infections

Fungal nail infections often start subtly with yellow or white spots, but can progress to nail thickening, flaking, or total detachment.
Recurrent infections might suggest a weakened immune system or poor circulation.
Toe pain

Pain in the toes shouldn’t be ignored. Common causes include overuse, arthritis, nerve issues, or even gout.
Any unexplained or ongoing pain deserves a professional evaluation.
White or spotted nails

White lines or specks – known as leukonychia – may result from minor trauma, but they can also signal nutritional deficiencies or infections.
If you spot such changes with no clear reason, it’s wise to investigate further.
Itchy and scaly skin between the toes

Itchy, peeling skin between your toes may be a symptom of athlete’s foot.
If untreated, this fungal infection can spread to your toenails, causing further complications. Early treatment is key to avoiding persistent issues.
