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 typically not needed. If it is very painful, a small procedure can be done (best within 48 hours) to release the blood pooled under the nails. In some cases, the nail may become warped or fall off before regrowing naturally.
