<s>[INST] Hi doctor, I have five small bumps appeared on the head of my penis after I had oral sex. It has been two months now, but it is still there. I have attached the photo. Also about two weeks ago I got rash on my hands, around the feet, and legs. When I consulted a doctor he said it is probably syphilis and gave me 2,400,000 units of Penicillin G shots. However, the results of blood test came back negative for syphilis. The result is rapid plasma reagin non-reactive. I am really confused whether the rash is related to oral sex or not. Please help. [/INST] Hi. I need few more details to guide you. Revert back with the answers for the above questions to a venereologist online --> </s>
