Are there any STIs whose symtoms are a flu-like condition?

dont panic, chances are it is just a normal virus, or maybe even something like glandular fever. whatever it is if u have had it 2 wks u should be going to the doctor to get it checked. from the info u have given it sounds unlikely to be an sti and i think it unlikely even it if is for it to be showing symptoms in 3 days. get a docs appt on monday to put yr mind at rest.
