I had sex with one partner without condom. After that am experiencing allergic reaction in my penis like reddish small blisters in glands and inside foreskin. After that I was consulted a skin doctor and he told it is fungal and maybe bacterial infection .he prescribed me clotrimazole cream and itraconazole tablet .i applied that cream it completely goes away. After six months it comes back .i repeated that medicine. After that I have tested for hiv and syphilis it comes negative. After one month I have visited std specialist he prescribed me for ictc and pcr test. It is also came as negative. But he told me your symptoms looks like genital herpes. Is there any test for particularly for genital herpes. Is herpes blister appear anywhere on the body?
