Mild Redness and Swelling in the Penis: Is it a STD? - Urology

Redness and swelling of the penile foreskin?


Hello, I would like to ask about a recent discovery of slight redness and swelling on both sides of the corona, which feels soft to the touch.
There are no ulcers like those shown in diagrams, and there is no noticeable abnormal discharge.
The redness and swelling have been fading over the past few days.
I have a problem with phimosis and had protected sexual intercourse about 16 days ago, during which there was also brief oral sex.
I would like to inquire whether this could be a symptom of a sexually transmitted infection.

Hello: Sexually transmitted infections (STIs) require blood tests for diagnosis and cannot be confirmed through examination alone.
However, your description indicates at least some inflammation, so it is essential to keep the area clean and dry.
It is important to get tested for STIs to understand your condition.
Wishing you good health.

More Info


When it comes to mild redness and swelling in the penis, particularly in the area of the corona and the shaft, it is understandable to be concerned about the possibility of a sexually transmitted disease (STD). However, there are several factors to consider before jumping to conclusions.

Firstly, the symptoms you describe—mild redness and swelling without the presence of ulcers or abnormal discharge—could be indicative of a few different conditions. One possibility is a mild irritation or inflammation, which can occur due to friction, allergic reactions to latex (if you are using condoms), or even irritation from soaps or other personal care products. Given that you mentioned having a long-standing issue with phimosis (a condition where the foreskin cannot be fully retracted over the glans), this could also contribute to localized irritation, especially if the foreskin is not able to retract properly during sexual activity.

The fact that the redness and swelling have been improving over the past few days is a positive sign. In many cases, mild irritation can resolve on its own with proper hygiene and care. It is also worth noting that STDs often present with additional symptoms, such as significant pain, unusual discharge, or systemic symptoms like fever. Since you have not experienced these additional symptoms, it may be less likely that you are dealing with an STD.

However, it is essential to consider your recent sexual history. Engaging in oral sex can carry some risk for STDs, even if the partner does not show any symptoms. Common STDs that can cause genital symptoms include herpes, gonorrhea, chlamydia, and syphilis. Each of these infections can present differently, and some may not show symptoms immediately.
Given your concerns, it would be prudent to consult a healthcare professional for a thorough evaluation. They may recommend a physical examination and possibly some laboratory tests to rule out any infections. Testing for STDs is a straightforward process and can provide peace of mind.
In the meantime, here are some general recommendations to help manage your symptoms:
1. Maintain Good Hygiene: Gently clean the area with mild soap and water. Avoid harsh soaps or products that could further irritate the skin.

2. Avoid Irritants: If you suspect that latex condoms may be causing irritation, consider using non-latex alternatives. Additionally, be cautious with any lotions or creams applied to the genital area.

3. Monitor Symptoms: Keep an eye on the redness and swelling. If it worsens, or if you develop new symptoms such as pain, discharge, or fever, seek medical attention promptly.

4. Consider Sexual Health: If you have had unprotected sexual encounters or are unsure of your partner's sexual health status, it is wise to get tested for STDs, even if you do not have significant symptoms.

5. Discuss Phimosis: Since you mentioned having phimosis, discussing this with a healthcare provider may be beneficial. They can provide options for treatment, which may help alleviate irritation and improve your overall sexual health.

In conclusion, while mild redness and swelling in the penis can be concerning, it is not always indicative of an STD. Monitoring your symptoms, maintaining good hygiene, and consulting with a healthcare professional will help ensure that you receive appropriate care and peace of mind.
