The most common cause of this condition is trauma to capillaries that are under the nail. The little capillaries burst and clot, leaving a thin and black line on nail. Often when thinking of trauma to the nail, you can think of a type of blunt-force trauma, like the one emanating from hitting the nail using a hammer. But, the trauma which leads to a splinter hemorrhage might not hurt at all.

When a client comes in having a splinter hemorrhage, then the doctor’s first response is to assist the client recall the event that led to the trauma. Explain that the hemorrhage is likely due to bleeding and clotting that is from tiny capillaries which run under nails.

Even though trauma is the common cause of a splinter hemorrhage, but it’s not the only cause. The condition can also be brought about by fungal infections or even from eczema, though in both cases, there would likely be other symptoms beyond the appearance of the hemorrhage.

Most of the time a splinter hemorrhage will be harmless; however, there is the slight possibility that the condition can indicate a serious infection in lining of heart. If a patient can’t remember when the trauma happened, and she has any other conditions indicating heart problems, the doctor should recommend an evaluation of the nails.

Black Lines in Nails What Does It Mean

When a person has dark stripes that are running down their nails, then the explanations might range from something that is normal through to severe, like melanoma.

A person is not supposed to ignore changes to nails, especially if they are very painful and without explanation.

  • There are several causes of the condition, which are both of no concern and serious.
  • Treatment usually depends on discovery of the underlying cause.
  • A person is supposed to see a doctor after noticing a change to their nails that cannot be explained by a trauma.

What are the causes?

In some of the cases, black line on nail is brought about by melanoma.

Most commonly, dark stripes on a nail are because of a symptom called linear melanonychia. According to the United Kingdom’s National Health Service, the stripes commonly happen in people of African-American descent who are above 23 years of age.

Linear melanonychia is said to be a normal fingernail color variation. The condition happens when pigments in nail called melanocytes produce excess amount of pigment. This leads to the nail beds darkening.

According to an article in the journal Podiatry Today, an estimated 55 percent of African-Americans are affected by linear melanonychia.

Less common causes of the condition exist. They include:

  • taking some of the medications, like chemotherapy drugs, anti-malarial drugs, or even the medication azidothymidine
  • Lupus
  • scleroderma

Another cause of black line on nail is a splinter hemorrhage, which happen when the blood vessels under the nail are damaged, often because of the injuries, like hitting.

More seriously, a black line on nail can indicate the presence of a skin cancer, which is a dangerous form of skin cancer also known as melanoma.

Melanoma under a fingernail is called the subungual melanoma.

According to clinical guidelines that was published in the Journal of Foot and Ankle Research, about half of all skin cancers on the hands and feet are due to ALM.

Horizontal Black Line on Nail

Though is said that western medicine arguably has the best diagnostic tools that are found in the world, it is sometimes scoffed at when the medicinal treatments only deal with the symptoms, not the underlying causes.

When dealing with the diagnostic symptoms that are related to nails, it might be very interesting due to the widespread autoimmunity that leads to asthma which is technically treated using an inhaler, but you can still see inflammation in nails using guidelines that are from eastern medicine.

Horizontal nail lines run from side to side of the nail. When forming within or even on the surface of nail itself, the horizontal nail lines are also known as Beau’s lines. When they are deeper and formed , they are known as Mees’ lines.

Previous injury to your nail bed

Nails grow at a high rate. This implies that an injury to nail bed won’t show up for several months, until it fully grows out. You might not remember months-old minor events which traumatized the nail bed enough so as to create the horizontal ridges.

To avoid this in future, be careful when working with your hands. Though we all know that cutting cuticles is a very bad idea, it’s a bad idea to push back your cuticles harshly. In people who have soft nails, this damages the nail bed with ridges which won’t show for several months.

Underlying health conditions

It can sound scary, but most of the conditions that are associated with the horizontal lines on your nails are already known to you.

According to doctors, sudden illness, malnutrition, and the pain as well as the stress of carpal tunnel syndrome might stop the nail growth. When the nail starts to grow out, it can lead to horizontal lines.

Arsenic poisoning, renal failure, or Chemotherapy

Arsenic poisoning, renal therapy, and also chemotherapy can also lead to horizontal black line on nail. However, unlike trauma, these issues form deeper Mees’ lines within the nails, as opposed to lighter surface lines which are Beau’s lines.

It is clinically advised that you see a doctor immediately if you think you have Mees’ lines, especially if you have other several symptoms of heavy metal poisoning.

Another condition, known as vasculitis, can also lead to black line on nail through an allergic reaction which damages the skin blood vessels.

Endocarditis and Vasculitis

Endocarditis results from germs which enter through several other areas of the body, like the mouth and thus infecting the heart. This rare condition usually emerges often in people who have existing heart diseases who undergo heart surgeries. People who are suffering from the condition normally develop painful skin lesions, like sores, blisters or even hives in several areas of the body.
