There may be erythematous itchy lesion in groin areas. It may be due to fungus like Candida albicans. I usually prescribe ketoconazole or ketoconazole tablets for two weeks and to apply clotrimazole cream. Wash the area with detail containing water. You may be alright. Still, you may consult dermatologist. I hope you got my answer. Thanks. Chat Doctor.  </s>
