Hello thanks for using health care magic Vaginal discharges and painful sex are caused by a genital tract infection. You have a genital tract infection and appropriate diagnosis and test need to be done to confirm the infection and give you appropriate treatment. You need to be screen for Pelvic inflammatory disease by use of ultrasound. You will also need to do a vaginal smear which will be examined microscopically as well as other tests such as KOH and pH tests of the discharge. Hope this helps Wishing you good health Dr Achuo
