People usually develop herpetic whitlows on one finger or thumb, but the infection can occur on multiple digits. A burning or tingling sensation in the affected area is the first symptom. The finger becomes red, swollen, and painful about a week after the first uncomfortable sensations. Small fluid-filled blisters appear in a cluster around a small, bright red patch of skin. Other symptoms include swollen lymph nodes in the elbows or underarm area and a mild fever.
