Thanks for the advice Oz. It is a good point to look into allergies and I will go and visit my doctor when my symptoms come back.
Concerning douching... I just wanted to include these articles so that people don't judge too quickly on this form of treatment: IngentaConnect Recurrent bacterial vaginosis-an old approach to a new problem
Bacterial vaginosis (BV) is a common cause of abnormal malodorous vaginal discharge and can be frustrating to manage in its recurrent form. Metronidazole is the standard treatment, but is unacceptable to many women when given repeatedly. Results of treating recurrent BV using a single vaginal washout with 3% hydrogen peroxide are analysed. A total of 30 symptomatic women with clinically confirmed recurrent BV in the absence of other genital infections were recruited after informed consent. Hydrogen peroxide (3%) was instilled into the vagina, left for 3 minutes and drained. Reassessment was at 3 weeks after treatment. A total of 23 women completed the study. Symptoms cleared completely in 78% (18/ 23), improved in 13% (3/23) and remained unchanged in 9% (2/23). All the 3 women with improved symptoms had a mild vaginal discharge, but only one of them was still able to perceive the malodour. The amine test was negative in all 23 women including the 2 (9%) who felt no change in their symptoms following treatment. Mixed anaerobes isolated in all women before treatment were not re-isolated, and microscopy did not show 'clue cells' in the vaginal discharge following treatment. Vaginal acidity was restored to normal in all but one (96%). No side-effects were observed in the treated women. Hydrogen peroxide (3%) used as a single vaginal wash was as effective as any other agent in current use in clearing the vaginal malodour of bacterial vaginosis at 3 weeks after treatment.
Also, from another source: Vaginal Infections - from Ronnie Falcão's Midwife Archives
As a midwife, I've become very enthusiastic about vaginal washes with hydrogen peroxide for yeast or anything pathogenic going on in the vagina, particularly because it's much safer than pharmaceuticals during pregnancy, even the over-the-counter kind. Hydrogen peroxide (H2O2) is very safe, breaking down into water (H2O) very quickly; as it does so, an oxygen atom is liberated, which oxidizes organic matter it comes in contact with on the surface of the vaginal mucous lining. It literally washes out and kills pathogenic organisms, including yeast, group B strep, and a variety of other vaginal pathogens. Hydrogen peroxide is normally produced as a byproduct of acidophilus metabolism, which is why acidophilus is a "friendly" vaginal bacteria - it provides a continual bath of hydrogen peroxide to keep those yeasty beasties and other pathogens from developing an overgrowth.
If you have any kind of vaginal infection that's causing troublesome symptoms, it makes sense to start with a vaginal wash while you're doing other things to help re-establish a more healthful acidophilus presence, such as Gy-Na-Tren. Do the vaginal wash while you're in the shower, and then apply your other treatments at a later time, usually at bedtime. One approach is to do the vaginal wash every night for a week, while starting other treatments. Once your symptoms are relieved, you might start spacing out the acidophilus vaginal suppositories to every other night and then only as needed to relieve symptoms.
[NOTE - This treatment is generally considered safe during pregnancy, but you should check with your healthcare provider first, in case there's something unusual about your situation. If your provider doesn't know anything about this treatment, you can suggest they educate themselves and let you know when they have the answer. If they suggest that alternative remedies are worthless and you should use a pharmaceutical agent instead, they are what I would call a word that starts with an "F" and rhymes with "Cool", or else they just really enjoyed the last conference sponsored by the pharmaceutical companies, and they want to ensure continuing pharmaceutical profits and conferences.]
There was also another medical article I read that I can't find that questioned the belief that BV is caused by douching. Sorry, I can't find it.
Anyhow, I don't mean to come across defensive about douching as a treatment option... just wanted to list these articles just FYI. Thanks again for your advice.
