There are several forms of ringworm that can affect the top layer of the skin. The condition is actually caused by a fungus, not a worm like the name implies. The term "ringworm" refers to the distinct circular rash seen in some forms of the infection. Other names for different ringworm infections include athlete's foot (tinea pedis), jock itch (tinea cruris), ringworm of the scalp (tinea capitis) or ringworm of the body (tinea corporis). Initial symptoms of ringworm may differ depending on which part of the body is impacted, but some of the primary symptoms are the same for all cases of ringworm.
Ringworm of the Skin
Jock itch, athlete's foot and ringworm of the body have similar symptoms, according to the National Library of Medicine (NLM). The skin may become red and itchy, and raised, scaly patches may develop, consisting of oozing blisters. These blisters are usually darker red on the outside with healthier-looking skin in the center. This is what gives ringworm its name. The skin may also appear abnormally light or dark. The Mayo Clinic explains that ringworm of the body can develop on the face or the trunk. More than one patch of ringworm may appear and new patches can pop up, overlapping the others.
Symptoms of jock itch are centralized to the groin, genitals, inner thighs, buttocks and anal area, according to the Mayo Clinic. The affected areas may burn or become more uncomfortable with tight clothing.
Scalp or Beard Ringworm
The scalp or beard develops bald patches when ringworm is present. The NLM suggests medical attention for ringworm of the scalp or beard. Other symptoms, as reported by the Mayo Clinic, include scaly, gray or reddened areas of the scalp, patches of small black dots in children with dark hair, brittle or fragile hair that is easily pulled out, or a tender and pain scalp. The first signs may be dryness and flaking before the rash spreads.
Ringworm of the Nails
The nails can become infected with fungus like any other part of the body. Signs of this include discoloration, thickness or crumbling, states the NLM. Darkness of the nail, dullness, lack of shine or nail shape distortion are other signs of nail fungus, according to the Mayo Clinic.
