Nail bed inflammation, known medically as paronychia, is an infection of the skin surrounding the nail. It can be acute or chronic and is often painful.
What is Nail Bed Inflammation?
Nail bed inflammation (medically known as paronychia) is an infection or inflammation of the nail fold -- the skin and soft tissue surrounding the nail on the sides and at the base. It is one of the most common conditions affecting the fingers and toes and can occur in both acute and chronic forms. People of all ages can be affected.
Causes
The causes differ depending on whether the condition is acute or chronic:
Acute Paronychia
- Bacterial infection, most commonly caused by Staphylococcus aureus
- Minor injuries, hangnails, or tears in the cuticle
- Ingrown nails
- Nail biting or finger sucking
- Manipulation of the cuticle
Chronic Paronychia
- Repeated or prolonged exposure to water, detergents, or chemicals
- Fungal infection, often caused by Candida albicans
- Skin conditions such as psoriasis or eczema
- Weakened immune system or diabetes mellitus
Symptoms
Symptoms vary depending on the severity and type of the condition:
- Redness and swelling around the nail
- Pain and tenderness in the affected area
- Warmth at the site of inflammation
- Pus-filled abscess in the case of bacterial infection
- Thickening and discoloration of the nail in chronic cases
- Separation of the cuticle from the nail plate
Diagnosis
Diagnosis is usually made clinically by a doctor through visual inspection and physical examination of the affected finger or toe. In cases of suspected fungal infection or treatment-resistant conditions, additional tests may be recommended:
- Swab and microbiological culture to identify the causative organism
- Fungal culture or PCR test if a mycosis is suspected
- Blood tests if an underlying systemic condition is suspected
Treatment
Home Remedies and Self-Care
For mild cases, the following measures can be helpful:
- Warm finger soaks in salt water or antiseptic solutions (several times daily)
- Protecting the affected finger from further trauma
- Avoiding prolonged exposure to moisture
Medication
- Antibiotic ointments or creams for mild bacterial infection (e.g., fusidic acid)
- Oral antibiotics for more severe or spreading infections
- Antifungal medications for fungal infections, applied topically or taken orally
- Corticosteroids combined with antifungals for chronic paronychia
Surgical Treatment
If an abscess (pus-filled pocket) has formed, a doctor may need to perform incision and drainage to release the collected fluid, relieve pain, and prevent the infection from spreading further.
When to See a Doctor
Medical attention is recommended if:
- pus is forming or pain is increasing significantly
- redness or swelling spreads to the finger or hand
- symptoms do not improve with self-care after a few days
- fever or general illness develops
- you have an underlying condition such as diabetes
Prevention
- Cut nails straight across and not too short
- Avoid injuring the cuticle
- Dry hands thoroughly after contact with water
- Wear protective gloves when working with water, chemicals, or dirt
- Avoid biting nails or chewing on the cuticles
