Hello Doctor. My Name Is Maureen And I’ve Been Having

Hello doctor. My name is Maureen and I’ve been having a problem since one month. I think I have a vaginitis or yeast infection as "Google" told me. I have all the symptoms that I read, but my discharge is not as described. It’s very thick and chunky, a little hard, and greenish kinda. It itches and I can’t go to the hospital because I don’t have insurance. Last month I used Monistat and it went away. But it came back three weeks later and I’m scsred I have it permanently. What médecine can i use? Thanks in advance.
