⚠️ When to Seek Medical Attention

Occasional, minor changes after a mild injury (like hitting your finger) are usually harmless. However, you should consult a doctor or dermatologist if you notice:

• A new, darkening, or expanding streak beneath a nail.
• Persistent blue or purple discoloration in your fingertips.
• Changes in nail shape (like rounding or lifting off the nail bed) without an obvious cause.
• Unexplained pain, swelling, or non-healing spots on your palms or fingertips.
