Hidden Clues: Your Nails May Signal Heart Danger
30 Apr
Summary
- Lines under nails, if not from injury, can indicate Endocarditis.
- Painful toe lumps, Osler nodes, suggest heart or blood vessel infection.
- Kawasaki disease in children causes rash, fever, and dry lips.

Unexplained lines beneath fingernails, if not attributed to trauma, can be an early indicator of Endocarditis, an inflammation of the heart's inner lining. This condition warrants medical attention.
Painful bumps on the toes, termed Osler nodes, are another sign suggesting an infection within the heart or blood vessels. Similar manifestations, known as Janeway lesions, appear as painless spots that typically resolve on their own but signal underlying heart issues requiring treatment.
In younger individuals, a combination of rash, fever, and intensely dry, cracked lips may point to Kawasaki disease. This illness primarily affects children aged six months to five years, impacting their blood vessels. While it can resolve spontaneously, untreated Kawasaki disease poses a risk of heart damage.
