What is subungual bleeding?

This is a purplish discoloration of the nails as a result from bleeding under the nail. This is caused by direct trauma.

Symptoms of subungual bleeding

  • Change in nail color

  • Black/blue/brown spots or moles, on the skin and lining of the mouth

Questions your doctor may ask to check for subungual bleeding

Your doctor may ask these questions to diagnose subungual bleeding

  • Has your nail color changed?

  • Are there black, blue, or brown spots on the skin or elsewhere? (Including moles)

Treatment for subungual bleeding

Treatment is usually unnecessary. If it is very painful, a small procedure can be done (best within 48 hours) to release the blood pooled underneath the nails. In some cases, the nail may become warped or fall off, before regrowing naturally.
