Definition
An ingrowing toenail is one that pierces the flesh of the toe. The sides or corners of the nail curl down and dig into the skin, causing swelling, pain and redness.
Cause
Improper cutting of toe nails
Tight shoes or hosiery
Tight socks
Abnormal shape of nail plate
Abnormal thickness of nail
Treatment & Prevention
Cut your nails straight across and don't cut too low at the edge or down the side. The corner of the nail should be visible above the skin. Also, cut them after a bath or shower when they're soft.
Avoid tight shoes and socks.
If discomfort occurs try soaking the feet in luke warm salt water for 10 minutes each day.
