Can gonorrhea be treated after 1 or 2 years?

Yes. However, because gonorrhea is a bacterial infection, it is generally treated with antibiotics. If gonorrhea has persist for more than 1 to 2 years, however, it may have spread to the joints and cause septic arthritis. Septic arthritis is inflammation of the joints by infection. It is not only more difficult to treat in general but also requires longer durations of antibiotics to treat than a normal case of gonorrhea.
