While the cause is often unknown, minor trauma most commonly precedes infection. It is a clinical diagnosis based on the presence of local pain, swelling, induration, and erythema. Early stages of felon may be managed conservatively with analgesics and antibiotics. Later stages require incision and drainage. Complications include fingertip soft tissue necrosis and osteomyelitis. Never bite or cut cuticles. Patient management is based on the patient’s baseline condition. The more severe the paronychia, the more visits the patient will need. The caregiver will follow the improvement or worsening of the condition.If the paronychia becomes better, fewer follow-ups are needed. and vice versa. If there is no improvement after 3 days of treatment (or if the paronychia worsens) the caregiver will change or add different or adjuvant topical and/or systemic treatment(s).
