Does trichomoniasis cause blisters?

Rarely: It usually just causes inflammation, but severe enough irritation can cause the skin to break down; it is not a common manifestation, though, and you should have your doctor investigate for other causes (such as hsv).

Trichomoniasis: Not usual presentation. Men may experience penile discharge, burning w urination & /or ejaculation as well as itching internal to the penis. Woman may have green/yellow/white or clear discharge & redness, itching, burning of tissues.
