A former nurse in her 80s with asthma and eczema presented to an urgent care clinic with a history of 1 to 2 weeks of left hand third digit pain. She denied trauma or nail biting and could not recall an inciting incident. She was noted to have a swollen, erythematous, and tender nail fold without purulence or nail discoloration. She received a diagnosis of an acute paronychia and was given instructions to use warm compresses. She was also prescribed an oral course of trimethoprim-sulfamethoxazole.
