Trichomoniasis or "Trich" is the most common sexually transmitted infection among young women. The symptoms of Trichomoniasis can include vaginal discharge that is greenish-yellow and frothy with a strong odor, pain when urinating or engaging in intercourse, vaginal itching and irritation, and, in rare cases, pain in the lower abdomen.
Trichomoniasis is caused by a tiny organism called Trichomonas vaginalis and is curable via treatment with antibiotics.
