I used to be red, swollen and itchy when it was hot, just like you. Later I went to the website to inquire about the situation. The expert said that I had an operation because my foreskin was too long to be treated. I have also asked many people in the same situation, and they all recommended me to Jinhua Tongji andrology hospital, saying that it is a professional treatment of andrology diseases. I went to that hospital myself, and now I'm fine, and there is no such symptom as itching. You can consult.
