As these cells are produced, older cells are pushed forward and compressed, giving rise to the typical growing pattern of the nail.
Within the nail bed is the germinal matrix, the source of cells that become the nail plate. So-called “capillary refill” indicates good flow.) (The function of these blood vessels can be assessed by compressing the nail to momentarily occlude them, and then releasing the pressure. The nail bed contains nerves, lymphatics and capillaries. The nail bed is the tissue that lies beneath the nail plate. The nail plate (which, in layman’s terms, is the “nail” itself) is a hard sheet of translucent keratin in which lie several layers of dead, compacted cells. The nail is a plate of keratin that covers the dorsal aspect of the distal phalanges of the fingers and toes (Figure 1). Last, the nail may display signs of underlying systemic disease. The nail is also susceptible to infection and may be the site of tumors, both benign and malignant. The fingernail is the most frequently injured portion of the finger secondary to its prominent location. In addition to protecting the fingertip, it provides tactile sensation, aids in thermoregulation, and assists in picking up small objects it also has dense lymphatics in the hyponychium that help resist infection. discoloration of the nail, which might look like a white, yellow, brown or green area.The fingernail serves multiple functions.Nail fungus causes changes to the infected nails, but how they look will vary with the type of fungus causing the infection. Wearing the same pair of sweaty shoes or boots every day can also be a culprit. If your nails (fingers or toes) are wet for a long time, this can also lead to nail fungus. If you walk where someone with a fungal infection walked, you can pick up and spread the fungus. Warm, moist places like pool decks and locker rooms can harbor the germs that cause fungal infections. Untreated, fungal infections can spread to other parts of your body and to other people.Ī fungal infection on the foot will often spread to one or more of your nails. When caught and treated early, you have a better chance to prevent further problems and your healthy nail can regrow. Nail infections should be examined to determine the best treatment to keep the condition from worsening and to help the nail grow normally.įungal nail infections are common and occur easily. The nail may become thick, hard, and deformed, as well. Acute paronychia can cause abscesses to form.Ĭhronic paronychia may cause the cuticle to break down and may eventually cause the nail to separate from the skin. Paronychia can happen in adults and children and usually begins with pain, swelling and redness around the base or the sides of the nail.
Chronic paronychia is usually caused by a fungal infection. Chronic Paronychia – lasts longer and may occur on your fingers or toes it either doesn’t get better or keeps coming back.Acute Paronychia – comes on suddenly, gets worse quickly and may not last long it usually occurs on fingers and is often bacterial.

Bacteria or a fungus introduced to the irritated or injured area can cause an infection of the skin at the base (cuticle) or up the sides of the nail. The skin becomes irritated or injured, often from picking at the nails, pulling hangnails, or biting on fingers. Paronychia is a skin infection around the fingernails or toenails.
