Generally, Red lines in nails can be related to:
- IgA Vasculitis (Henoch-Schonlein Purpura)
A disease that causes inflammation and bleeding of small blood vessels, commonly affecting the skin, joints, intestines, and kidneys. This can lead to rashes, stomach pain, and kidney damage. Though it can affect anyone, it is more common in children under 10 years old. The cause is not well understood, but it may result from an immune system issue.
- Vasculitis (including Cryoglobulinemia)
A condition where the body's immune system attacks blood vessels throughout the body, causing inflammation. The vasculitis can impede blood flow and cause tissue or organ damage. There are many different types of vasculitis, each with its own triggers including infection, medications, and cancers.
- Scleroderma
Scleroderma is a connective tissue disorder that causes the skin to thicken and harden, though it may also affect other organs. It is categorized as localized or widespread (systemic scleroderma). It is a disorder where the immune system mistakenly attacks its own body.
- Ischemic Colitis
- Giant Cell Arteritis (Temporal Arteritis)
Related Serious Diseases
Sometimes, Red lines in nails may be related to these serious diseases:
- Kawasaki Disease
Kawasaki disease causes swelling, called inflammation, in the walls of small to medium-sized blood vessels that carry blood throughout the body. Kawasaki disease most often affects the heart arteries in children. Those arteries supply oxygen-rich blood to the heart. It also causes swelling in glands, called lymph nodes, and mucous membranes inside the mouth, nose, eyes and throat. Symptoms include a fever greater than 102.2 degrees Fahrenheit (39 degrees Celsius) for five or more days, a rash on the main part of the body or in the genital area, an enlarged lymph node in the neck, very red eyes without a thick discharge, red, dry, cracked lips and a red, swollen tongue, swollen, red skin on the palms of the hands and the soles of the feet. Later the skin on fingers and toes peels.
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Do you have bleeding under your nails in 2 or more places?
- How long have you had bleeding under a fingernail or toenail?
- How has bleeding under a fingernail or toenail changed since it started?
- How often do you experience bleeding under your nails?

I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
