Description of your vaginal discharge
and itching around vagina & perineum suggest that this discharge is something different form the yeast infection. Such watery discharge, slightly greenish in colour and frothy is due to trichomonal infection. It does cause immense itching. It can be treated by Metronidazole
would not cause lymphadenopathy
in the groin. It seems, you have got some superadded bacterial infection - mostly Lymphogranuloma venerum or Gonorrhoea
. These are sexually transmitted infections (STI). Does your partner also has any trouble? This will require antibiotics treatment. Both of you will have to undergo the treatment simultaneously and till that you will have to observe sexual abstinence.
Agreed that both of you wee tested for STI; however it was about 18 months ago. During 18 months, there are many opportunities for such infections. So please, both of you report to STI specialist for investigations and treatment.
I hope you got required guidance from this.
