Hi,Thanks for the query to HCM.
-I studied your query in depth and understood your concerns.
-Cause and Treatment-of the bump on penis-
-In your case the cause mostly is -penile
warts due to HPV-as they are painless and recurred after the solution.
-The lumps are mostly HPV warts which go after podophyllum solution application.
-I would advise you to
consult Dermatologist if they recurr for removing your worry, by
second opinion.
This would help you to plan treatment with your doctor.
Don't worry and things will settle
Hope this would resolve your query.
Welcome further for any query in this regard.
Wishing you a fast recovery.
Don't forget to Write a good and strong review ASAP for the benefit of other patients.
Have a Good Day.
