Hello dr. i had ulcer on my penis inside almost 7 year back ( during this infection i did masturbate also) after this infection i have been fever,?

Syphilis? Herpes?: The most common causes of genital ulcer are herpes and syphilis, especially if sexually active at the time. If a single painless ulcer, syphilis is the main concern. That could have caused fever in the next few months, but not a new fever 7 years later. If the ulcer was painful, if more than one ulcer, or if recurrent outbreaks, probably herpes. In any case, see a doctor for sure.
