It is rare to acquire any STD by performing cunnilingus. And when STDs infect the pharynx, they almost always are asymptomatic--that is, STDs rarely cause sore throat and to my knowledge no STD has ever been reported to cause "fleshy bumps" (or any other kind of bumps) in the throat. Almost certainly you have a garden-variety respiratory virus, unrelated to your October oral sex events.
Good luck-- HHH, MD
