Hello Dr.
Du,
Two days ago, I developed several very small blisters on my foreskin (this is the first time).
There is a slight burning sensation, but it is not itchy, and it feels uncomfortable when it rubs against my clothing.
Please see the attached image: https://aku5670.blogspot.com/2021/03/blog-post.html?m=1.

After researching similar conditions and articles online, I suspect it could be genital herpes or balanitis.
Due to my occupation, I have been working at sea for an extended period, and because of the pandemic, I have not been on land for over six months.
My last sexual encounter was more than eight months ago, and I have a stable sexual partner (my wife), so the likelihood of contracting genital herpes seems low.

I have emergency medications on board, such as acyclovir, that comply with regulations.
If it is uncertain whether this is genital herpes, should I take the medication? If it is not herpes, how should I utilize the onboard medical facilities for treatment and care? (Due to work commitments, I cannot easily go ashore for a consultation.)
I appreciate your time in responding to my inquiry.
Thank you.

Hello: 1) This platform stipulates that diagnosis cannot be made without a proper examination and is for reference only.
If your lesion has scabbed over, simply keep it clean and dry.
Ensure you get enough rest, as herpes is often a reactivation of a previous infection, presenting as blistering lesions (due to weakened immunity, so it's important to pay attention to rest and nutrition).
2) Personally, I recommend against using acyclovir, as it only shortens the duration of the outbreak by a few days.
Self-administration may lead to side effects, which could worsen your condition.
Therefore, your primary tasks are: 1.
Strengthen your immune system, and 2.
Keep the lesion clean and dry.
Wishing you good health.

More Info

Understanding small blisters on the foreskin can be concerning, especially when they are accompanied by discomfort. Based on your description, it seems you are experiencing small blisters that are causing a mild burning sensation but not itching. Given your situation—being at sea for an extended period and having limited access to medical care—it's important to consider several potential causes and appropriate treatments.

The small blisters you are experiencing could be attributed to a few different conditions. One possibility is balanitis, which is inflammation of the glans (the head of the penis) and can occur due to various factors, including irritation from soaps, detergents, or friction from clothing. Another possibility is herpes simplex virus (HSV) infection, which can manifest as small, painful blisters in the genital area. However, since you mentioned that you have not had sexual contact for over eight months and have a stable partner, the likelihood of a new herpes infection is reduced but not entirely ruled out.

Other potential causes could include:
1. Contact Dermatitis: This could result from irritation due to soaps, lotions, or even friction from clothing. If you have recently changed any products you use, this could be a factor.

2. Folliculitis: This is an infection of the hair follicles that can lead to small, blister-like bumps.

3. Fungal Infections: Yeast infections can also cause irritation and blistering in the genital area.

4. Other Viral Infections: Besides herpes, other viral infections can cause similar symptoms.

Given your limited access to medical care, here are some steps you can take to manage your symptoms:
1. Maintain Hygiene: Keep the area clean and dry. Use mild soap and avoid any harsh chemicals or fragrances that could irritate the skin.

2. Avoid Irritants: If you suspect that clothing or products may be causing irritation, try to minimize contact with those items. Loose-fitting underwear can help reduce friction.

3. Topical Treatments: If you have access to over-the-counter hydrocortisone cream, it may help reduce inflammation and discomfort. However, avoid applying any topical treatments without knowing the exact cause of the blisters.

4. Acyclovir: If you suspect that the blisters could be herpes and you have a history of herpes outbreaks, taking acyclovir may be beneficial. However, it is essential to consult with a healthcare professional before starting any antiviral medication, especially if you are unsure of the diagnosis.

5. Monitor Symptoms: Keep an eye on the blisters. If they worsen, become painful, or if you develop additional symptoms such as fever or systemic illness, it would be prudent to seek medical attention as soon as possible.

6. Avoid Sexual Activity: Until you have a clearer understanding of the cause of your symptoms, it is advisable to avoid sexual activity to prevent potential transmission of any infectious agents.

In conclusion, while it is possible that the small blisters on your foreskin could be due to a variety of causes, including irritation or infection, proper hygiene and monitoring your symptoms are crucial. If the condition does not improve or worsens, it is important to seek medical attention as soon as you are able to do so. Your health and well-being are paramount, and addressing these symptoms promptly can help prevent complications.
