Have they cultured the skin lesions recently to confirm it is still GC? GC is getting very resistant to antibiotics so if you were on one and it didn't get better and they have confirmed it is still GC then they will probably switch antibiotics. I agree a molecular test which requires a urine or swab for the genital area and a swab into the lesions will be the best test.

10 years ago i had DGI with skin lesions.i was treated with antibiotics for a month.couple of month ago skin lesions began to reproduce.can it be not properly treated old gonorrhea infection?
why do you think it is dissemenated GC? Have you been tested previously and what symptoms do you have?
Urine or swab test would still pick up the bacteria.
