Yes, you can get gonorrhea again. You can get it from an untreated partner or a new partner.
Can gonorrhea reappear years later?
If gonorrhea remains undetected and undiagnosed for a long period of time, the infection is likely to spread and affect other parts of the body. Patients who have carried the infection for a long time are at risk of complications and may begin to experience gonorrhea symptoms months or even years after infection.
Can you still have gonorrhea after treatment?
If you still have symptoms after you finish your treatment, call your doctor. Even if you finish your treatment and the gonorrhea is totally gone, it's possible to get infected with gonorrhea again. Gonorrhea isn't a one-time-only deal. So use condoms and get tested regularly.
