How to Tell If Your Toenail Is Ingrown or Infected

An ingrown toenail typically announces itself with tenderness along the side of your nail, right where the edge meets the skin. The earliest sign is often a focused, pressing pain when you touch the area or wear shoes, even before you notice visible changes. Knowing what to look for at each stage helps you decide whether you can manage it at home or need professional care.

The Earliest Signs

The first thing most people notice is pain along one side of the toenail, usually the big toe. It feels like something sharp is pressing into the skin when you push on it or when a shoe squeezes the toe. At this point, the nail edge has started digging into the soft tissue beside it, but the damage is still minor.

Look closely at the skin next to your nail. In the early stage, you’ll see mild redness and slight puffiness right where the nail curves into the skin fold. The area may feel firm or swollen to the touch, but you won’t see any fluid or drainage. The skin might also feel warmer than the surrounding toe. On darker skin tones, the color change may look more like a deepening of your natural skin color rather than obvious redness.

A simple test: press gently along the side of the nail. If you feel a sharp, localized sting right at the nail border rather than a dull ache across the whole toe, that’s a strong indicator the nail is growing into the skin.

What an Infected Ingrown Toenail Looks Like

If an ingrown nail goes untreated, bacteria can get into the broken skin and cause infection. This is a clear escalation from the early stage, and it looks and feels noticeably different. The redness spreads wider, the swelling becomes more pronounced, and the pain shifts from pressure-sensitive to more constant. You may feel throbbing even when you’re not touching the toe or wearing shoes.

The hallmark sign of infection is discharge. You’ll notice fluid seeping from the nail fold, ranging from clear to yellowish or white. In some cases, a small pus-filled pocket forms along the side of the nail. The skin around it will feel warm, and the tenderness intensifies so that even light contact, like a bedsheet brushing against it, causes pain.

Signs It Has Become Severe

A long-standing or repeatedly irritated ingrown nail can reach a more advanced stage where the body produces granulation tissue, sometimes called “proud flesh.” This is a small, red, bead-like growth of extra tissue that forms along the nail fold. It bleeds easily when bumped and adds to the swelling and pus drainage. If you see a fleshy, moist bump growing over the edge of your nail, the condition has progressed significantly.

At this stage, the skin around the nail may also start to overgrow, partially covering the nail edge. The combination of granulation tissue, overgrown skin, persistent drainage, and pain makes the toe look visibly different from its normal shape. In rare cases, a more serious infection can develop, bringing fever along with the local symptoms.

How It Differs From Nail Fungus

People sometimes confuse an ingrown nail with a fungal infection because both can make a toenail look abnormal. The distinction is straightforward once you know what to check. An ingrown nail causes pain, redness, and swelling focused on the skin beside the nail. A fungal infection changes the nail itself: it becomes thick, discolored (often yellow or brownish), and brittle or crumbly. Fungal nails rarely hurt unless the infection is advanced, and the surrounding skin usually looks normal.

If your nail looks discolored and rough but the skin beside it isn’t red, swollen, or tender, you’re likely dealing with fungus rather than an ingrown nail. It’s also possible to have both at the same time, since a thickened fungal nail can press into the skin and trigger ingrowth.

What Causes a Nail to Grow In

The most common culprit is trimming your nails too short or rounding the corners, which encourages the edge to grow into the skin as it lengthens. Tight or narrow shoes push the skin against the nail border, creating the same effect from the outside. Other contributors include toenail injuries (stubbing, dropping something on the toe), naturally curved nails, and sweaty feet that soften the surrounding skin and make it easier for the nail to pierce through.

Some people are simply more prone because of their nail shape. If you’ve had one ingrown toenail, you’re more likely to get another, especially on the same toe.

When Home Care Is Enough

If you’re in the early stage, with mild redness, slight swelling, and pain only when pressed, you can usually manage it yourself. Soak your foot in warm water for 15 to 20 minutes a few times a day to soften the skin and reduce swelling. Gently lift the edge of the nail away from the skin fold using a small piece of clean cotton or dental floss tucked underneath, giving the nail room to grow out over the skin instead of into it. Wear open-toed shoes or roomier footwear until the tenderness resolves.

This approach works best when there’s no sign of infection. If soaking and lifting the nail doesn’t improve things within a few days, or if pain gets worse, it’s time for professional treatment.

When Professional Treatment Is Needed

Once infection sets in, with pus, significant swelling, or worsening pain, the situation typically requires more than home soaking. A doctor can numb the toe and remove the portion of the nail that’s digging into the skin. This is a quick in-office procedure that provides almost immediate relief.

For ingrown nails that keep coming back, a more permanent option involves removing the nail edge and treating the growth area so that strip of nail doesn’t regrow. This prevents the same section from curling into the skin again. The decision between a simple trim and a permanent correction generally depends on how inflamed the tissue is and how many times the problem has recurred. If granulation tissue has formed or the skin has overgrown the nail edge, a partial removal is almost always the recommended approach.

Recovery from a partial nail removal is typically a week or two of mild soreness, with the toe looking fully normal within a few months as the remaining nail grows out.
