What Are the Common Causes of Fingernail Pus?
It is usually caused by stab wounds, abrasions, nail inlays, or "prickles" after the nail groove and its nearby tissues. Sub-adenial abscesses are often caused by the spread of paronychia, or infections caused by stab wounds in the nails, or secondary nail infections caused by pinch crush injuries. The pathogenic bacteria are mainly Staphylococcus aureus.
Hypothyroidism
- It is an inflammatory response to skin folds around the nails. Because of frequent wet impregnation, such as chefs, fish merchants, laundry or silk reeling workers, the nail folds are macerated and easily separated from the nail profile, and they are affected by Pseudococcus, Pseudomonas aeruginosa, Candida and Proteus infection.

In severe cases, the nail can completely loosen. Fall off. At the beginning, redness, swelling and pain occur on one nail sulcus. It can be purulent in a short time. The infection can spread to the nail root and the contralateral nail sulcus. At this time, the pain is intensified, and the swelling is obvious. Yellow and white pus can be seen under the nails. If the nails are not treated in time, it can develop purulent finger inflammation, even cause phalangeal osteomyelitis, and it can become chronic paronychia. It will last forever. Paronychia or sub-parietal abscess, because the infection is superficial, the systemic symptoms are often not obvious.
Treatment of sub-adenitis abscess
- In the early days, topical antifungal agents and fungicides such as terbinafine hydrochloride ointment and neomycin ointment can be used alternately. In the future, Karst tincture can also be used to remove excessive granulation tissue from the nail margin. Avoid injury to the nail bed during surgery. .

Anesthesia or local anesthesia can be used for the finger root and finger nerve block; raise the affected limb with a rubber band around the root of the finger to temporarily block finger blood flow; then perform surgery. Unilateral paronychia can be cut longitudinally after the nail is opened, and the skin margin is lifted to clear the pus cavity and placed in an oil gauze to drain. The posterior nail fold can also be removed by a small piece. If the infection has spread to the surrounding nails or under the nail Abscesses, depending on the extent of the infection, remove some or all nails.
