Skin infection around testicles.

Hello Sir/ Mam I suffered with a skin infection in testicles last month. My testicles turned red and cause itching and also some swelling was there.I went to Doc and he suggest me to use Zydip C cream in affected area and eat levocitrizine twice a day. It improved my condition. But after a week taking above medication It started itching in my whole body so I stopped the above medicines thinking that itching in my body is due to reaction of medication in body. After somedays when itching my body stopped I started taking levocetirizine tablets. So I think itching in my body is due to zypid c cream. Now I am taking levocetirizine tablets 5mg daily in night from last 3 days again. Will only taking levocetirizine improve my condition ? Please suggest me. Now I am not using any cream on affected area. I have attached pics of current skin condition.
