What could cause pain on the side of my nail, and how can I address it?

When you feel pain along the side of your nail, it is often because the nail is growing into the nearby skin. This is called an ingrown nail, and when it happens, the skin can get red, swollen, and sore. Another cause could be an infection in the skin around the nail, which might occur if germs get into small cuts or breaks in the skin. Sometimes, small injuries or repeated pressure from tight shoes can also cause discomfort in that area. To help manage the pain, you can soak the affected nail in warm water for about 15-20 minutes a few times a day. This can reduce swelling and soften the skin so the nail does not hurt as much. It is also important to trim your nails straight across instead of rounding the edges to prevent them from growing into the skin. Over-the-counter pain relievers can help ease discomfort.
