I had unprotected oral and vaginal intercourse with a person of questionable cleanliness. At 5 weeks, I developed a sore throat, low grade fever (99.5-100.5 F), a two distinct lesions inside my lower lip (two canker sore like lesions and multiple little bumps that were not push filled). The back of my throat is red, but there are no visible lesions or exudate. I am only coughing after meals for the most part. I had a full STI panel at that time, but everything was negative. Is this gonorrhea or syphilis or another STI that needs to be specifically orally screened for, or is this maybe strep?
