Concerns about syphilis infection?


Hello doctor, a week ago I had a deep kiss and performed oral sex without a condom with a stranger (but the other person did not ejaculate).
I am very worried about whether I might have contracted syphilis.
A few days after the incident, I noticed that my foreskin was red and swollen (which could also be due to masturbation, as I have experienced this before).
I also found two red spots on the glans (they are not painful, itchy, or raised), and my tongue has similar signs of sores.
The other person is my age and is certain that they do not have any sexually transmitted infections (we are still in contact), but I am still a bit concerned.
I would like to ask you, doctor, whether the symptoms I am experiencing could be signs of a syphilis infection.
Thank you very much for your response.

Hello: If a sexual partner does not have syphilis, transmission is not possible.
The diagnosis of syphilis is made through a blood test and cannot be determined by appearance.
You may refer to the syphilis section of the Centers for Disease Control.
Wishing you good health.

When it comes to concerns about sexually transmitted infections (STIs), particularly syphilis, after engaging in unprotected oral sex, it's essential to understand the risks involved and the nature of the symptoms you're experiencing.

Firstly, syphilis is primarily transmitted through direct contact with syphilis sores, which can occur on the genitals, anus, or mouth. While the risk of contracting syphilis through oral sex is generally lower than through vaginal or anal intercourse, it is still possible, especially if there are sores or lesions present in the mouth or genital area of either partner. In your case, since you engaged in unprotected oral sex, there is a potential risk of exposure to syphilis if the other person was infected.

Regarding the symptoms you mentioned—redness and swelling of the foreskin, red spots on the glans, and the appearance of sores on your tongue—these could be indicative of several conditions. It's important to note that many STIs, including syphilis, can present with non-specific symptoms that may overlap with other conditions. For instance, irritation from masturbation or other non-infectious causes could also lead to similar symptoms.
In the case of syphilis, the primary stage typically presents with a painless sore called a chancre at the site of infection, which may not always be noticeable, especially if it is located in the mouth or on the genitals. However, the symptoms you describe do not specifically align with the classic presentation of syphilis, particularly if they are not painful or itchy.

Given your concerns, it is advisable to seek medical attention for a thorough evaluation. A healthcare provider can perform the necessary tests to determine if you have syphilis or any other STIs. Testing for syphilis typically involves blood tests that can detect antibodies to the bacteria that cause syphilis. It's important to note that testing should ideally be done at least three weeks after potential exposure to allow for accurate results, as there can be a window period where the infection may not be detectable.

Additionally, if you are experiencing symptoms such as sores in the mouth or unusual lesions, it would be prudent to consult a healthcare professional who can assess these symptoms in person. They may refer you to a specialist, such as a dermatologist or an infectious disease expert, for further evaluation and management.

In conclusion, while your symptoms may not definitively indicate a syphilis infection, it is crucial to get tested and evaluated by a healthcare professional to rule out any STIs and to address your concerns. Engaging in safe sexual practices, including the use of condoms and regular STI screenings, can significantly reduce the risk of transmission and help maintain sexual health.
