Hello, Yes, diabetes can cause itching in the body. Itching can be caused by a fungal infection (candidiasis), dry skin, or poor circulation. Based on history, you seem to have developed jock itch (fungal infection of the groin). Candidiasis can create itchy rashes of moist, red areas surrounded by tiny blisters and scales. These infections often occur in warm, moist folds of the skin like armpits, groin, between the fingers and toes. People with diabetes are more susceptible to developing infections, as high blood sugar levels can weaken the patient s immune system defenses. I advise you to: -Apply the antifungal creams such as Miconazole or Clotrimazole twice daily.  -Limit how often you bathe, particularly when the humidity is low.  -Use a mild soap with moisturizer and apply skin cream after bathing and -use loose cotton undergarments. Consult your doctor for the control of blood sugar. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Mohammed Taher Ali
