If the tip of the nail is yellow, this usually indicates smoking or a fungal infection. However, it can also be due to excessive use of dark nail polish. If the entire nail is yellow and thicker, symptoms of chronic bronchitis or other respiratory diseases may be present.
You can restore your nail’s natural color with this simple home remedy: Add a glass of apple cider vinegar to a container of water and soak your infected nail for 20 minutes. Repeat this process regularly until you notice a change.
How thick are your nails?
Paronychia is an inflammation of the fingertip that causes the tip to swell so much that it covers the nail . The most common cause is lung disease or a lack of oxygen. Other factors may include intestinal inflammation, liver disease, or AIDS. If this applies to you, see a doctor as soon as possible.
Splinters in the nails
If a splinter becomes lodged in your finger, you’ll notice vertical bleeding or a blood clot under your nail. However, the same subungual bleeding can occur without a splinter and is a sign of endocarditis (an infection of the lining of the heart).
