Hello,
Itching,burning and
yellowish green discharge can be due to trichomoniasis.It
does not seem like dermatological. The characteristic symptom of trichomoniasis infection is a heavy, frothy, yellow-green, fishy-smelling discharge from the vagina. The infection can also cause discomfort during sex, vaginal itching, pain when passing urine and occasionally stomach pains.
It is diagnosed by pelvic examination, swabs of the discharge and their culture sensitivity.
