That would only treat chlamydia. It is not effective for gonorrhea. You need to follow up with a second opinion from a doctor who is willing to make sure you are tested and treated properly.
I have used this before doxycycline
No i were not tested for that but the doctor prescribed antibiotics for that
Unfortunately, all you can do is see a different doctor for second opinion. You have been tested several times, but were you tested for chlamydia/gonorrhea?
