Throat Discomfort After Sexual Encounter: STI or Pharyngitis? - Urology

Infection issues


Hello Doctor, after visiting a sex worker, I have been experiencing occasional throat phlegm, itching, and a sensation of something foreign in my throat.
I'm unsure if I have a sexually transmitted infection (STI) or pharyngitis.
I've been feeling uncomfortable for a while and have undergone blood and urine tests for gonorrhea, chlamydia, HIV, and syphilis, all of which came back negative.
If there is an issue with my throat, can blood tests still provide results? (Since the affected area is different?) My genital area has no issues; if the other person did not have genital warts, would I still be at risk of infection? Can blood tests detect genital warts? I'm very concerned, and being abroad makes things more complicated.
I've read a lot, and could it just be pharyngitis?

Hello: If there is no oral sex, the likelihood of throat issues is low.
HIV testing requires 3 months due to the window period.
As for genital warts, they are not easy to diagnose, and blood tests cannot confirm them.
However, they do not typically appear quickly.
It is advisable to seek medical attention for your condition, as even pharyngitis requires treatment.
Wishing you good health.

More Info


After engaging in sexual activities, particularly with sex workers, it is understandable to have concerns about sexually transmitted infections (STIs) and other health issues. Your symptoms, including throat discomfort, phlegm, itching, and a sensation of something being stuck in your throat, can be indicative of several conditions, including STIs, pharyngitis, or other infections.

Firstly, it is important to note that oral sex can indeed pose a risk for certain STIs, including gonorrhea, chlamydia, and syphilis, even if there are no visible symptoms on the genitalia. If the sex worker had an STI, it is possible to contract it through oral contact. The throat can become infected, leading to symptoms such as sore throat, discomfort, and phlegm production.
You mentioned that you have already undergone testing for gonorrhea, chlamydia, HIV, and syphilis, and the results were negative. This is reassuring, but it is essential to understand that some STIs may not be detectable immediately after exposure. For example, HIV can take several weeks to months to show up in tests, and other infections may have similar windows.
Regarding your throat symptoms, it is possible that they could be caused by pharyngitis, which is an inflammation of the throat that can be due to viral or bacterial infections. Common viral infections, such as the common cold or influenza, can lead to throat discomfort and phlegm. Bacterial infections, such as streptococcal pharyngitis, can also cause similar symptoms.
To address your specific questions:
1. Can blood tests detect throat infections? Blood tests are generally not used to diagnose throat infections. Instead, a throat swab is typically taken to identify bacterial infections like strep throat. Viral infections usually do not require specific testing and are diagnosed based on symptoms.

2. Can I contract an STI from oral sex if the partner does not have visible symptoms? Yes, STIs can be transmitted even if the infected person does not show any symptoms. Therefore, it is crucial to consider the risk of STIs in any sexual encounter, regardless of visible signs.

3. Can blood tests detect all STIs, including HPV (which causes genital warts)? Blood tests can detect certain STIs, but HPV is primarily diagnosed through visual inspection or specific HPV tests, not through standard blood tests.
4. What should I do next? Given your ongoing symptoms and the anxiety surrounding potential STIs, it would be advisable to consult a healthcare provider. They may recommend a throat swab to check for bacterial infections and possibly additional STI testing if deemed necessary.
5. What about self-testing kits? Self-testing kits for STIs can be useful, but their accuracy can vary. It is generally recommended to follow up with a healthcare provider for comprehensive testing, especially if you have symptoms or concerns.

In conclusion, while your negative test results are encouraging, it is essential to remain vigilant about your health. If your throat discomfort persists or worsens, or if you develop new symptoms, seeking medical attention is crucial. Additionally, practicing safe sex, including the use of condoms during oral sex, can significantly reduce the risk of STIs in the future.
