Receiving unprotected oral sex and developing the symptoms you described 9 days later, could indicate that an STI has passed to you. You would need to visit a clinic where they could review your medical and sexual history, as well as any medication you may be taking now. They would also look at your symptoms and do some tests. If it is an STI, it could be gonorrhea from what you have described or another type of STI that causes similar symptoms.
If it is gonorrhea from the same person it’s possible that it was passed to the person from a new partner or maybe it is an ongoing partner who was not treated the first time. It is common for most STI not to show symptoms, this is why we recommend that if someone has a positive result for say gonorrhea that all sexual partners over the previous 2 months get tested and the treatment.
We also recommend that people who have had gonorrhea in the throat and have had treatment for it get a test of cure to make sure it has gone. There has been some resistance to gonorrhea seen around the world as well, so it would also be a good idea to get a gonorrhea culture done if at anytime you are concerned that the medication did not work. The gonorrhea culture allows us to see if there is any resistance to certain antibiotics.
