Written by Medicover Team and Medically Reviewed by Dr Rajitha Alluri , Dermatologist


Have you noticed tiny red or brown streaks under your nails that look like splinters? These are called splinter hemorrhages, which are small blood clots that can signal anything from minor injuries to serious health conditions. In this guide, we will break down what causes them, how to recognize concerning symptoms, and the best treatment options, whether it is simple care at home or medical intervention.

What are the Symptoms and Warning Signs of Splinter Hemorrhage?

Splinter hemorrhages are among the earliest visible signs of nail bed injury or systemic disease. Spotting them early can lead to quicker diagnosis of potentially serious conditions such as infective endocarditis or autoimmune disorders.

Common Symptoms

  • Red or brown lines under the nails
  • Pain or tenderness around the nails
  • Changes in nail color or shape

Severe Symptoms

  • Persistent or spreading discoloration
  • Nail deformity or detachment
  • Signs of systemic illness (fever, fatigue, joint pain)

What are the Different Types of Splinter Hemorrhage?

Understanding the various types of splinter hemorrhages is crucial because their appearance can reveal the underlying cause. Categorizing them helps direct appropriate diagnosis and treatment.

Recognized Types

  • Infective endocarditis splinter hemorrhage caused by a bacterial infection in the heart lining
  • Traumatic splinter hemorrhage caused by direct injury to the nail bed
  • Vasculitis splinter hemorrhage resulting from inflammation of blood vessels due to autoimmune disease
  • Nail psoriasis splinter hemorrhage linked to psoriasis affecting the nail bed
  • Systemic lupus erythematosus (SLE) splinter hemorrhage seen in individuals with lupus

What are the Common Causes and Risk Factors of Splinter Hemorrhage?

How is Splinter Hemorrhage Diagnosed?

Accurate diagnosis of splinter hemorrhages involves evaluating the nail appearance along with a deeper look into your overall health. This process helps distinguish harmless trauma from serious medical conditions.

Diagnostic Procedures

  • Visual examination of nails
  • Medical history review
  • Nail bed assessment
  • Dermoscopy
  • Nail fold capillaroscopy
  • Blood tests for infections or autoimmune markers

What are the Treatment Options for Splinter Hemorrhage?

Managing splinter hemorrhages is about more than treating what's on the surface. Proper care focuses on resolving the root cause to prevent recurrence.

Medicover's Treatment Approach:

  • Observation for mild or traumatic cases
  • Treating underlying conditions such as infections or autoimmune diseases
  • Topical treatments including anti-inflammatory or antifungal creams
  • Oral medications such as antibiotics, antifungals, or immunosuppressants
  • Surgical treatment in complex or recurrent cases

When Should You See a Doctor for Splinter Hemorrhage?

Seeing a doctor at the right time can help catch serious illnesses early. Unexplained or persistent splinter hemorrhages should not be ignored, especially if other symptoms are present. Prompt evaluation ensures the right treatment is started without delay.

High-Risk Groups

  • Individuals with heart valve conditions
  • Patients with autoimmune diseases
  • Diabetics and hypertensive patients
