What is paronychia?
Paronychia is inflammation of the skin around a finger or toenail. Acute paronychia (> 6 weeks) is usually caused by a bacterial infection. Chronic paronychia (persisting > 6 weeks) has an unknown cause and can become secondarily infected.
- Acute paronychia usually follows a break in the skin between the cuticle and the nail plate due to:
- Ingrown toenails
- Oral retinoids and chemotherapy
- Chronic paronychia occurs in people with hand dermatitis or who have constantly cold and wet hands.
- Diabetics and immune suppressed patients are at risk.
- Acute paronychia The nail fold becomes red, swollen and painful. Yellow pus may appear under the cuticle
- Chronic paronychia The affected nail fold gradually becomes swollen, creating a space between the nail plate, allowing organisms and irritants to enter.
