Red, Infected Skin Beside Toenail: Home Care and When to See a Podiatrist

Paronychia (nail fold infection) or ingrown toenail with cellulitis requires prompt care:

Immediate Home Measures

1. Clean gently: Mild soap, lukewarm water; pat dry.
2. Antiseptic: Dilute povidone-iodine or chlorhexidine; avoid full-strength hydrogen peroxide (tissue toxicity).
3. Warm soaks: 15 min, 3–4×/day with Epsom salts; promotes drainage.
4. Protect: Non-adherent dressing, loose footwear, avoid pressure.
5. OTC analgesia: Ibuprofen or acetaminophen.
6. Do not attempt "bathroom surgery" (cutting, digging).

Red Flags for Podiatrist/ER

• Spreading erythema, streaking, warmth
• Fever, chills
• Purulent drainage
• Diabetes, PAD, immunocompromise
• No improvement in 48–72 hours
• Suspected foreign body (splinter, glass)

Professional Treatment

• Incision & drainage if abscess
• Partial/total nail avulsion for ingrown nail
• Oral antibiotics if cellulitis (cephalexin, clindamycin, TMP-SMX)
• Underlying cause correction (trimming technique, footwear, orthotics)

Diabetics: any foot infection = urgent evaluation.
