Rashes on any part of the body create a feeling of uneasiness for the individual. There are many types of rashes. The cause of the inner thigh rash is the fungal infection called as Jock Itch or tinea cruris. This particular fungal infection is found in the groin region of the human body. For the growth of this particular infection, warm and moist atmosphere is ideal and any individual, who wears sweaty or wrapping clothes around the body in the winter, produces the warm atmosphere for the fungus to grow. The occurrence of the Jock Itch is more common in men than in women. The Trichophyton rubrum fungus causes the Jock itch that produces the inner thigh rash.
The inner thigh rash caused by the Jock itch infection starts in the groin region and continues on both the sides. This infection progresses down the inner thighs. The area that is being affected looks redder than the one that has been infected by the fungus. The affected part seems rough and is easily distinguishable. Some other rashes of the inner thigh resemble the Jock itch rashes and the individual should consult the physician for the right diagnosis of the rashes. The similar rashes that resemble the inner thigh rash are the intertrigo and fissures.
Diagnosis of the inner thigh rash
Since the inner thigh rash is caused by the Jock itch infection, it is always better to check for the fungus. The KOH test diagnoses the Jock itch for the hyphae and this can be seen under the microscope. In this diagnosis, a scalpel scratches the infected part and the dead skin is collected onto a glass slide, drops of Potassium hydroxide are put and the slide is heated. The KOH tests thus can diagnosis the Jock itch for the inner thigh rash.
Treatments for the inner thigh rash
The use of topical creams and ointments help in the relief of inner thigh rash. Since the infection is only on the upper part of the skin the topical medications work best. The antifungal medicines require prescription by the physician but there are some OTCs or the over the counter medicines that help to treat the infection. The OTCs include tolnaftate, clotrimazole, and miconazole. In avoiding the Jock itch, one has to take preventive measures as well.
