[/INST] Hi, Thanks for writing in. If you have itching in the scrotum and allergy and fungal infections have been ruled out then chronic skin conditions need to be evaluated. Some people have Chat Doctor.  It can be a hypersensitive dermatitis to any soap or clothing which has gone unnoticed. Any chronic bacterial infection in the area is also to be investigated. Please apply steroid containing ointments over the itching areas and watch for relief. It is important to consult a dermatologist and get clinically examined. Please keep your genitals  </s>
