Jock itch (tinea cruris) is an infection within the groin that is caused by a particular type of fungus called ringworm. Though anyone can develop this infection, males who frequently sweat, such as athletes, are most commonly diagnosed with this condition. The symptoms of jock itch typically resolve following treatment with an antifungal medication. Discuss jock itch symptoms with a doctor if they occur to ensure appropriate medication is received.
Groin Itching
The most common symptom associated with jock itch is itching within the groin region, explain medical professionals at Medline Plus, a health information website established by the National Institutes of Health. Itching sensations can be uncomfortable and may extend from the groin to the upper thighs or anus. This contagious infection can be spread to other people through contact with contaminated clothing or infected skin. Frequent scratching can further irritate the affected skin and may increase a patient's risk of spreading the infection to other parts of the body. Sensations of itching can be mild to severe and may worsen until treatment is received.
Skin Lesions
Patients with jock itch can develop abnormal skin lesions across the groin region. These skin lesions typically appear as an elevated, circular rash that is dry or flaky, explains Kids Health, a children's health information website supported by the Nemours Foundation. Certain patients can develop fluid-filled blisters within the genital region as a symptom of jock itch. These blisters may burst, causing excess fluid to ooze from the skin lesion, reports Medline Plus. These symptoms may also be accompanied by sensations of burning, which can be uncomfortable. Excessive sweating, physical activity or tight clothing can worsen skin lesion symptoms in certain patients.
Skin Discoloration
Skin discoloration can occur as a symptom of jock itch in affected patients. The infected skin region may appear red, inflamed or irritated. Certain patients may also notice patches of skin that appear darker or lighter than normal, reports Medline Plus. Symptoms of skin discoloration can occur within any region of the groin, including the genitals, anus or upper thighs. With treatment, these skin discoloration symptoms typically resolve completely.
