i have noticed one vaginal cyst at left side of my vaginal passage,it pains sometimes in morning for few seconds,sometimes it secretes paleyellow fluid with bad odour.and also pains during intercource.iotherwise its normal,ts been more than year now. :-( one doctor suggested me sonogrphy before 8 months but my sonography reports were absolutely normal that time.i m very confused please suggest the test which will prove the cyst,and also some medications.
