Did you have oral gonorrhea or genital?
Burning mouth syndrome has a lot of causes, and it's often hard to pinpoint the one that is causing it for you.

Medications can cause it, but it's particularly high blood pressure meds that cause it. What meds did you take for your gonorrhea?
Oral gonorrhea can cause a burning sensation, so I'm curious as to what meds you took, and if you gave oral sex. If you didn't give oral, you can't have oral gonorrhea.
