STD Testing and Symptoms: Your Concerns Addressed - Urology

I hope the doctor can respond~ Thank you?


Hello, doctor.
I would like to ask a question.
I had unprotected sexual intercourse in mid-August 2015, followed by unprotected oral sex.
Because I was worried about sexually transmitted infections (STIs), I got tested three times: at the end of August, mid-October, and mid-December.
The results showed no STIs.
However, I had developed some small white spots, about the size of a pinhead, on my foreskin.
Later, I underwent circumcision.
Over the past few months, I have noticed many small, pimple-like bumps on my skin (on my hands, sides of my waist, and chest).
They can be squeezed to release white substance, but they are neither painful nor itchy, and they have not gone away; in fact, they seem to be increasing in number.
I have seen several doctors and taken many medications, but nothing has improved.
I really don’t know what to do.
Doctor, what is the window period for STIs? It has been about four months from my last sexual encounter to my last blood test.
If the report says everything is fine, does that mean I am truly in the clear? What are the symptoms of STIs? I hope you can reply to me.
Thank you.

When it comes to concerns about sexually transmitted diseases (STDs) and the symptoms you are experiencing, it's important to approach the situation with both caution and clarity. Based on your description, you have taken proactive steps by getting tested multiple times after your sexual encounter, which is commendable. However, the presence of new skin lesions and your ongoing concerns warrant further discussion.

Firstly, let's address the concept of the "window period" for STD testing. The window period is the time after exposure to an STD during which the infection may not be detectable by standard tests. This period varies depending on the specific STD. For example, HIV can take up to 3 months to show up in tests, while other infections like gonorrhea and chlamydia may be detectable within a week or two. Since you mentioned that you were tested at intervals of about 2 to 4 months after your exposure, it is likely that you were outside the window period for most common STDs, assuming you had no further exposure.

Regarding the symptoms you described—small white bumps on your skin that are not painful or itchy—these could be caused by a variety of factors. It's essential to consider that not all skin lesions are indicative of an STD. Conditions such as folliculitis, keratosis pilaris, or even benign cysts can present similarly. However, if these lesions are persistent and increasing in number, it is crucial to seek a thorough evaluation from a dermatologist or a healthcare provider who specializes in skin conditions. They may recommend a biopsy or other diagnostic tests to determine the exact nature of these lesions.

It's also worth noting that while your STD tests came back negative, it’s still important to maintain regular check-ups and communicate openly with your healthcare provider about any new symptoms or concerns. If you have ongoing anxiety about STDs, consider discussing this with a mental health professional who can help you manage these feelings.

In summary, while your previous tests indicate that you likely do not have an STD, the new skin symptoms should be evaluated by a specialist. The window period for testing varies by infection, and your proactive testing is a positive step. Always prioritize open communication with your healthcare providers, and do not hesitate to seek further evaluations if your symptoms persist or worsen. Remember, your health and peace of mind are paramount, and there are professionals available to help you navigate these concerns.
