 [ Symptoms ] i had yeast infection doctor gave me pill it didnt work i used monasat 7 i am still in pain and discharge can it be std i had discharge and pain i went to my doctor she gave me medicine for yeast infection it helped for a bit then it came back i spoke to her she said i should use i think monasat 7 i used it and it helped a bit now every time after and during sex with my boyfriend my vagina burns and hurts sometimes there is a thick discharge can it be a std or another yeast infection [ Disease ] i do not have any way of knowing if your vaginal discharge is an std or not since i can not examine you look at the discharge under a microscope or test it in a lab nor do i know your sexual history or your boyfriend is sexual history the only thing you can do if your doctor is treatment is not working is to go back be re examined and be tested this time by a vaginal culture or smear a person can have a yeast infection and something else so if you are worried about an std that something else will need to be specifically tested
