Subungual hematoma is the medical term for bleeding and bruising under the nail. This is usually the result of some kind of injury to the blood vessels under the nail bed. For example, blood vessels can break and leak blood into the area underneath the nail when a door slams on a finger or a heavy object crushes a toe.
What does it mean when your toenail looks bruised?
If you’ve recently dropped something on your foot or stubbed your toe on something, your nail discoloration could be a symptom of a subungual hematoma. This injury can also result from wearing shoes that are too tight. Subungual hematomas can make your nail appear red or purple.
Does a bruised toenail go away?
With a subungual hematoma, the pain typically goes away in a few days. The nail itself will take longer to recover. The discolored nail will eventually grow out — or in some cases it may fall off or need to be removed — and be replaced by a new, healthy one.
What happens if you don’t drain blood under nail?
If blood is spontaneously draining from the hematoma, drainage of subungual hematoma is generally not required. You should not try draining your subungual hematoma at home as improper drainage may result in infections or permanent damage to the nail bed.
How do I know if my toenail is fungus or bruised?
If the spot is black and shiny, it is likely a bruise and less likely toenail fungus, especially if you recall when or why that bruising might have occurred (example, if you stubbed your toe). If the discoloration is yellow, gray, or greenish in tint, it is more likely a toenail fungus infection.
How long does it take for a bruised big toenail to grow out?
Regardless of treatment the hematoma will eventually be resorbed by the body and a new nail will grow out. On average the nail takes 6 to 9 months to grow completely out.
What do you do with a dead toenail?
Clean your toe, making sure you remove any debris, and apply an antibiotic ointment. Cover the area where your toenail fell off with a bandage. Seek immediate treatment if your entire toenail falls off or the area around your toenail won’t stop bleeding.
Why are my two big toenails bruised?
The most common culprit for a black toenail is blood under the hard tissue. Damage to the end of the toe causes blood to leak through the nail bed and stain the keratin a dark color. This is also known as a subungual hematoma, or a bruise under the nail.
