An ingrown toenail occurs when the nail edge grows into the surrounding skin, causing localized pain, redness and sometimes infection. This page explains common causes, simple self-care measures and when to get professional assessment, as general information rather than personal medical advice.
What causes an ingrown toenail?
An ingrown toenail most often affects the big toe. Common contributing factors include cutting nails too round, tight or narrow footwear, repeated pressure or trauma, and changes to nail shape from infection or fungal disease. Family tendency and certain long-term health conditions can increase complication risk.
Typical signs and when to pay attention
Look for pain, localized redness, swelling at the nail edge and occasional yellowish drainage. Persistent or worsening pain, increasing redness or spreading warmth, difficulty walking, or any signs of systemic illness (fever, widespread redness) warrant prompt professional assessment.
Home care and how to reduce recurrence
Simple measures may help mild cases: trim nails straight across without rounding the corners, avoid overly tight shoes, keep feet clean and dry, and choose roomy footwear. Short warm foot baths can ease symptoms temporarily. These measures are general supportive actions—not substitutes for medical evaluation when severe symptoms or infection are present.
Which specialist to consult
For recurrent or infected ingrown nails, consider podiatry (foot care specialist), dermatology or foot/orthopaedic surgery depending on severity. Specialists evaluate the nail and surrounding tissue, advise on conservative options, and if needed arrange procedures aimed at resolving persistent problems. People with diabetes or circulation problems should seek earlier medical advice.
