⚠️ Your Toenails Could Be Warning You About Serious Health Problems
Foot specialists say changes in your toenails may reveal important clues about your overall health — and some signs should never be ignored.
Experts warn that dark discoloration, especially a painful black vertical line on one nail, could be a sign of subungual melanoma, a dangerous form of skin cancer that develops under the nail.
Other warning signs include:
✔️ Nail pain or bleeding
✔️ Splitting or slow healing after injury
✔️ Pus or discharge
✔️ Nails separating from the nail bed
Doctors say early detection is critical, as untreated cases can become life-threatening.
Not all discoloration means cancer — yellow, white, or green nails may also signal conditions like psoriasis, infections, kidney issues, or liver disease.
