Don't rip off the hangnail, as it can worsen the condition. If your symptoms worsen or don't clear within a week, consult your doctor. You should also consult your doctor if you're experiencing severe pain, major swelling of the finger, excessive pus, or other signs of infection.

What happens if you don't treat hangnails?

“If you don't cut the hangnail back, it could continue to get traumatized and take a very long time to heal,” Collyer warns. “If the cuticle swells or becomes painful, you should see your doctor to ensure there is not an infection,” Collyer says.

Why are hangnails so painful?

Hangnails are often seen at the end of a digit near the nail. There are many blood vessels and nerve endings in this part of the nail. Hangnails also cause inflammation and swelling that may press on the nerve endings. As a result, it can lead to more pain and irritation.
