Can protopic be used on the genitals: foreskin, shaft, head of penis? is mild tingling sensation normal?

For what?: It all depends on what type pf symptoms you are having. Probotic is usually prescribed for atopic dermatitis(eczema) which is mostly seen on other areas. If on perineal area usually happens on groin area. I would suggest you get evaluated first since this medication should not be used or used cautiously if there are other issues going on. See your doctor for exam and treatment.
