If the edge of the big toenail becomes sore, red, and painful in shoes, it may be an ingrown toenail. The nail edge presses into the surrounding skin and irritates it. If the pressure keeps going, the nail fold can become inflamed, the toe can swell, and the area may start to ooze.
The goal of home care is to reduce pressure, keep the skin clean, and stop the nail corner from digging deeper. Do not cut the nail too short or round the corners.
What causes it#
A common cause is cutting the nail too short or rounding the corners. Narrow shoes, small socks, toe shape, heavy sweating, and repeated sports pressure can also add to the problem.
Early symptoms#
At first the side of the nail is sore, red, and sensitive to pressure from shoes. The pain is often worse when walking or when the toe is pressed from the side.
If inflammation develops, the pain may become throbbing and continue at rest. The toe may swell and ooze pus.
What can be done at home#
Wear wider shoes and socks so there is less pressure on the nail edge. Wash the foot gently and dry the toe carefully. If the skin is intact and the irritation is mild, do not dig into the nail corner. Let it grow out.
Trim nails more straight across next time and leave a little length. If needed, smooth the edge with a file so it does not stay sharp.
Shoes, socks, and exercise#
A narrow shoe pushes the toes together and increases pressure on the nail fold. In a suitable shoe, the toes have room to lie straight.
If the toe hurts after exercise every time, the shoe size, shape, and lacing should be checked.
Extra caution in diabetes#
If you have diabetes, reduced foot sensation, poor circulation, or a condition or medicine that weakens immunity, take an ingrown toenail seriously. Small infections can progress without being noticed quickly.
Do not dig at the nail with sharp tools. In higher-risk situations, professional foot care or healthcare assessment is safer.
When to seek care#
Seek care if the toe oozes, the pain is throbbing, redness spreads, walking becomes difficult, or home care does not settle the symptoms within about a week. Seek care also if the problem keeps returning.
If you have diabetes, reduced foot sensation, or circulation problems, seek care early.
