Inflammation at the bases of the nails is most likely related to which event?

• A. Trauma
• B. Allergy
• C. Fungal infection
• D. Bacterial infection

Answer: (A)

Inflammation around the nail base usually starts from injury to the surrounding skin. When the skin at the nail folds is damaged by activities like aggressive grooming, nail-biting, or minor hits, the body's inflammatory response kicks in, producing redness, swelling, and tenderness in that area. This local trauma creates a breach that can trigger inflammation more quickly than other causes. Allergic reactions can irritate the area, but they typically present as dermatitis with itching or diffuse skin involvement rather than a localized, injury-related flare at the nail base. Fungal infections alter the nail itself—often causing discoloration, thickening, or crumbling—rather than causing acute base inflammation. Bacterial infections can occur, but they often arise after or alongside trauma rather than being the initial event themselves. So the most likely initiating factor for inflammation at the bases of the nails is trauma.
