Blood Under Fingernail
A heavy impact or crushing action to the fingernail can break the blood vessels under the nail resulting in the accumulation of blood under the fingernail. The blood accumulates under the fingernail and gives a red, maroon or black appearance to the fingernail. There can also be pain due to the pressure exerted by the accumulated blood or due to the injury itself.
Blood under the nail is also known as subungual hematoma.If the size of the area of blood under the fingernail is less than twenty five percent, then home care is sufficient. However, if the pain is intense and the area of blood under fingernail is more than twenty five percent, consulting a doctor is recommended.
Treatment For Blood Under Fingernail :
Applying a cold compress for fifteen to twenty minutes can relieve the pain and reduce the inflammation. Anti-inflammatory medications such as Motrin or Advil can also be used.
If the blackened area under the nail grows in size or if the pain is severe, it is recommended that you consult your doctor. They will drill a small hole into the fingernail and drain the accumulated blood. This will get rid of the discoloration and pain. Your doctor may also further check the nail for injury, and fractures etc. In some cases, healing would require removal of fingernail.
Blood under a fingernail is a common problem and in most cases, the discoloration goes away as the fingernail grows. Sometimes, the nail becomes black and falls off. If this happens it is usually replaced by a new fingernail.
Some people recommend relieving blood under the fingernail by puncturing the darkened skin (where it joins with the nail) using a sharp object. However, this method can lead to pain or infection. Consulting a doctor to remove the accumulated blood is a much better option.
