Hi, I had a protected sexual encounter in feb 2014 with a csw , after 3-4 days i get burning sensation on my penis, pain in testis, some back pain, & a clear discharge when squezing the penis, there seems to be very minute raised bump near the urthera opening which never causes any issue issue & also a very minute pus filled on the lower part of the shaft where the skin toches the penis head, all urine culture were negative through out till three months
