What Causes Itchy Yellow Blisters On Penis And Swollen Lymph Nodes?

Hi, I'm having an issue in my genital region, I had a clear blister on my penile shaft which popped and turned into 6-8 little yellow bumps. They itch but are not painful. I also have severely swollen lymph nodes, all signs point towards herpes, is there anything else it can be?

Thanks for contacting HCM

I am sorry to hear that you have been having blisters on your penis with associated lymph nodes. I agree with you that the most likely cause is herpes infection. But since the blisters ruptured and now you have additional bumps these lumps could be secondary bacterial infection. In this case you would need treatment for both the herpes and for secondary bacterial infection.

Another cause could be syphilis as it can cause a non painful open sore on the penis. There are several other STD that can cause open sores and lymph node enlargement.

I recommend that you seek medical attention to help diagnose and give you the proper treatment.

In summary
1. open sores penis
2. Probable STD
3. Possible causes Herpes, bacterial secondary infection, syphilis, Lymphogranuloma venereum
4. Seek medical attention for proper diagnosis and treatment

I hope I answered your question. Please contact HCM again with your medical questions and concerns
