Fingernails provide a degree of protection to the soft, sensitive tissues underneath them. The National Library of Medicine reports that the nails are made up of hardened layers of a protein called keratin. Healthy nails are smooth and have a uniform color. Fingernail infection is caused by bacteria or fungus that gets underneath the nail. There are several symptoms that you may see when you have this condition.
Look of the Nail
Some nail infections, particularly the fungal ones, can cause a thickening of the nail. This thickening can cause a change or distortion in the nail. Ridges or lines may also form on the nail. According to the Mayo Clinic, the nail will lose luster or shine and become very dull looking. The nail may also become ragged, or may even crumble off in layers.
Color of Nail
When a person has a fingernail infection, there may be a change in the overall color of the nail. Some nail infections cause the nail to yellow or can even turn a dark color or black in some cases. The Mayo Clinic reports that the dark coloring of a nail can be caused when debris has gotten under the nail and caused the infection.
Swelling and Redness
Around the nail bed, the finger may become red and start to swell. This is sometimes caused by a condition called cellulitis. The skin may look very irritated and may even have pus that leaks out. At this point, if you haven't already, you should see your physician because antibiotics are needed to relieve these symptoms.
Foul Smell
Some fingernail infections will have a very bad smell. This usually occurs in severe infections or infections that have been allowed to fester without seeking medical assistance. The foul smell can be caused by a fungus that has invaded the nail, a worsening infection, or the death of tissue surrounding the nail bed. If medical help is not sought, the infection can get into the blood stream and cause a more serious, life-threatening condition called sepsis.
Pain
Pain commonly occurs when a nail infection worsens. The pain can also be caused by the loss of the nail itself. The skin and tissues around and underneath the nail are sensitive. However, when an infection invades this area, it can cause swelling and pressure that push on these already sensitive areas causing it to become increasingly painful. This pain may persist until the infection itself is treated.
