An ingrown toenail occurs when the edge of the nail grows into the surrounding skin. It can be symptomatic or asymptomatic — meaning some people have pain without infection, while others develop swelling, redness, or pus.
Ingrown toenails can happen at any age, from young children to older adults, but they are especially common in teenagers and young adults.
Moist, soft skin makes it easier for the nail edge to dig in and become irritated.
Flexible joints can cause the toes to roll inward, increasing pressure on the nail edges.
A tight Achilles can alter gait and increase pressure at the front of the foot, pushing the nail into the skin.
If the foot rolls in or out excessively, the nail edges may be overloaded, leading to irritation and ingrowth.
Tight shoes
Narrow toe boxes
Hard school shoes
These squeeze the toes and push the nail into the skin.
One of the most common causes.
Problems include:
Cutting nails too short
Cutting down the sides
Leaving sharp corners
Tearing nails instead of trimming
Long nails can curve and press into the skin, especially in active children or adults wearing tight shoes.
Symptoms
Pain along the nail edge
Redness or swelling
Tenderness when wearing shoes
Clear discharge
Pus (yellow discharge) if infection develops
Pain without infection (very common)
Pain, redness, and swelling (needs attention)
Overlapping/overgrowing soft tissue (same as photo)
Follow the natural shape and line of the nail
Do not cut nails too short
Avoid digging down the sides
Use clean, sharp nail clippers
Smooth sharp corners with a file
These steps can help reduce discomfort but do not replace professional care:
Soak the foot in warm water with salt for 10 minutes
Helps soften the skin, reduce swelling, and ease pain
After soaking, gently massage the skin away from the nail edge
Helps reduce pressure and encourages drainage if pus is present
Avoid tight shoes
Wear open‑toed rigid footwear if possible
Without proper care, an ingrown nail can:
Become infected
Develop proud flesh (granulation tissue)
Cause ongoing pain
Lead to repeated flare‑ups
Make walking or sport uncomfortable
A podiatrist can:
Safely trim or reshape the nail
Remove the offending nail edge
Reduce inflammation
Provide long‑term solutions
Address underlying causes like gait issues, Achilles tightness, or footwear problems
Persistent pain
Recurrent ingrown nails
Pus or signs of infection
Difficulty trimming nails
Pain affecting walking or sport
