Which symptom may indicate a fungal infection in nails?

• A. Discoloration and thickening
• B. Constant pain
• C. Sudden nail growth
• D. Increased flexibility

Answer: (A)

Discoloration and thickening of the nails are key symptoms that may indicate a fungal infection. Fungal infections, often caused by dermatophytes or yeasts, can lead to visible changes in the nail structure. Discoloration may manifest as yellow, green, or brown patches, while thickening occurs as the infection progresses, causing the nails to become more brittle and distorted. These symptoms are indicative of the body’s response to the infection, making them essential for diagnosis.

In contrast, constant pain, sudden nail growth, and increased flexibility do not typically align with the symptoms of a fungal infection. Constant pain might suggest other types of injuries or conditions affecting the nail bed or surrounding areas but is not commonly associated with fungal infections. Sudden nail growth can occur due to various reasons, including health improvements or underlying conditions, and is not a specific indicator of fungal infections. Increased flexibility, on the other hand, is more likely tied to nail health and hydration and does not signify a fungal issue. Thus, discoloration and thickening remain the most telling signs of a fungal infection in nails.
