i have had a problem with yellow discharge for years now. It first started when i had unprotected sex. So i assumed i had contracted an STI. However, my Dr has tested me for all STI's, yeast, etc and can not find a cause. All swabs and urine tests have come back normal. Except for a low growth of Group B strep. The discharge has a burning sensation, I have stomach pains, pain sometimes with sex, painful periods, excessive lubrication with sex.. There isnt a stong odor however. My Dr has treated me with Metronidazole- brand name used was flagyl Nylstatin for yeast, clamycin,spandnox (for yeast), and recently had some relief with Augmentin(which was prescribed for a chest infection). When i was on augmentin all the above symptoms went away however came back 1 or 2 days after i came off the anti biotic. Dr said that if it went away on Augmentin then it must be bacterial - but why would he then prescribe a yeast medication (spandnox -sorry about spelling) - wouldnt augmentin make yeast worse? Has anyone has a similar situation and had success treating the infection?? What was it treated with successfully? Is it possible this is a problem related to Group B strep?? Im pretty desperate to find a solution..
