Trichomoniasis symptoms that come and go

Trichomoniasis is caused by a parasite and can be present when symptoms are mild or absent. When symptoms are noticeable, a person may have changing discharge, genital itching, irritation, burning during urination, or discomfort during sex. A [Vaginal Discharge](/symptoms/vaginal-discharge/) or [Vaginal Itching](/symptoms/vaginal-itching/) page may help you record details such as colour, smell and timing.

Symptoms that come and go can also occur with other vaginal conditions. A temporary improvement after a period, sex, washing, or an unprescribed product does not identify the cause.

Book testing if you have symptoms, a partner with an infection, or a possible sexual exposure. Note when symptoms appear, any medicines used, and whether a partner has been treated. Until you receive advice, consider pausing sex or using barrier protection and avoid sharing prescribed medicine.

If testing confirms trichomoniasis, take the clinician-prescribed medicine as directed. Partners may need assessment and treatment at the same time. The [Antibiotic Treatment for Pelvic Infection](/treatments/medical-gynaecology/antibiotic-treatment-for-pelvic-infection/) page provides related treatment context, although your clinician should choose the appropriate medicine.

Seek prompt care for pelvic pain, fever, vomiting, unusual bleeding, faintness, or symptoms during pregnancy. Do not wait for a quiet interval if these signs are present.

Return for review if symptoms persist or recur after treatment. Reinfection, another condition, or the need for a different assessment may be considered.

Could my symptoms have another cause? Which test should I have and when? Should partners be treated? What should I do if symptoms return after finishing medicine?
