I had unprotected oral sex with a sex worker on the 2nd of October. Around 20 days later I started having a tingling sensation, pain and irritation on the left side of my penis. I visited the doctor on the 1st of November. He said it's nothing and advised bixigard tablet and terbiforce ointment for 10 days. The pain hadn't moved an inch till then. On 15th November, I underwent blood and urine tests and were negative for HiV , VDRL. The usg scan for penis, abdomen and Doppler for scrotal were normal as well. I masturbated once after that and had intolerable pain on the left region of my penis. Recently I had tests for herpes and HIV by prc method and the results were negative as well. When I retract the foreskin, I can see a minute trail ofwhite dots. It has been almost 45 days since I am having these symptoms of tingling sensation, mild pain and discomfort. Could you help me out ?
