The symptoms of ringworm are quite distinctive, and when combined with an understanding of the common risk factors for ringworm, they can make a diagnosis easier. Fortunately, ringworm treatments are available over the counter in many regions, but if a ringworm treatment doesn't work within a week, it may be necessary to see a doctor to confirm ringworm is the problem and gain access to stronger medications . People who suspect they have ringworm should be aware that they are highly contagious to other people and to pets such as cats and dogs.
Before delving into the symptoms of ringworm, it may be helpful to know more about ringworm. Despite the name, this skin condition is not caused by worms. It is actually the result of an infection with a fungus, and it can appear in various places on the body, including the scalp, beard, groin, skin, and feet. Doctors refer to ringworm as "ringworm," often adding a term to describe the location, as in the case of ringworm pedis, tinea pedis, also known as athlete's foot.
The most common risk factor for ringworm exposure is exposure to an environment where the fungus can thrive. Gyms tend to be harbors for the fungus, as it can live on the warm, moist floors of places like showers and locker rooms, transferring to the feet of gym users. Ringworm is also common in crowded settings. Children tend to be at higher risk due to community sports areas, as are athletes. People who work or live with animals may also be at risk, because ringworm can also live in cats and dogs. If ringworm symptoms appear in people at higher risk, it is very likely that ringworm is the cause, rather than another skin condition.
Ringworm usually starts as a small reddish area on the skin that can be slightly scaly and itchy. As the fungus settles, the area will become distinctly scaly, and may also blister and ooze. Classically, a white ring appears around the reddish area, which explains the term "ringworm," and the site is often very itchy. If ringworm attacks the hands and feet, the nails can begin to crumble and peel off.
Ringworm especially loves the folds of the skin, because they are moist, dark and warm. Ringworm symptoms often begin between the toes, in the groin creases, and behind the ears. In cases where ringworm develops on the scalp or under the beard, it may take some time for the ringworm to become noticeable, as the itching may subside until the reddish area becomes apparent. Hair loss can also occur with ringworm in these areas.
Treatment for ringworm involves applying a topical antifungal to kill the fungus. In cases where the scales have broken open and become infected, an antibiotic may be prescribed. It is also important to wash all clothing that ringworm has come into contact with and avoid touching people, pets, carpets, and drapes with an active ringworm infection. If ringworm symptoms appear in other household members, they should be treated immediately to prevent the fungus from spreading.
