I had these redness or pink spots for 1.5 years. Sometimes my foreskin got irritated as well. Many doctors, different medications (antibiotics, fluconazole for fungus, steroid creams and home remedies. Unfortunately nothing helped me. Then I went to see an urologyst and told me I had recurrent balanitis and he recommended me to circumsice my penis. After thinking for a long time about and looking that my penis didn't heal with the medications , I went for the surgery. One year already and no redness spots anymore. Your problem may be different than mine, therefore make an appointment with an urologyst and if you want more information, you can send me messeges at my inbox. Good luck!!
Hello,
This redness can be due to friction rub, contact dermatitis or chafing. Wash the areas several times with fresh water. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. Also wear cotton undergarments. Application of mild corticosteroid cream and oral antiinflammatories like ibuprofen/acetaminophen are also helpful. If the symptoms are severe then it will be best to consult a dermatologist.
