Why Do My Fingernails or Toenails Hurt?

Common Causes

Healthy nails are shiny, pink, and shouldn't feel uncomfortable. However, various factors can cause nail pain, including:

Improper Nail Care: Excessive filing, cutting, or biting can damage the nail and cause pain.
Trauma: Injuries to the nail, such as a stubbed toe or a hammer falling on your finger, can cause pain and discoloration.
Fungal Infections: Fungus can enter the nail through cracks or trauma, causing it to thicken, discolor, and become painful.
Allergic Reactions: Some people are allergic to nail polish, removers, or other nail products, which can result in inflammation and discomfort.
Weak Nails: Certain medical conditions, such as thyroid problems or vitamin deficiencies, can weaken nails and make them prone to breakage and pain.

In addition to the general causes mentioned above, pain associated with acrylic nails can arise from:

Acrylic nails that are too thick or applied unevenly can put pressure on the nail bed, causing pain.

Attempting to remove acrylic nails at home without proper tools or technique can damage the natural nail, leading to pain.

Some people may be allergic to the chemicals used in acrylic nail products, which can manifest as redness, swelling, and pain around the nails.

Frequent application and removal of acrylic nails can weaken the natural nails, making them more susceptible to breakage and pain.
