Hi Thank you for asking HCM. I have gone through your query. Greenish discharge can be due to trichomonas vaginalis infection. A swab test will be helpful to rule out the condition. For such condition in my patients I would recommend using metronidazole as vaginal suppository or as oral tablets. Using intimate wash daily will be helpful to normalize vaginal bacterial flora and PH also. Hope this may help you. Let me know if anything not clear. Thanks.
