Ladies please try this wonderful vaginal probiotic called FloraFemme. It's a prescription strength, very effective suppository which balances your vaginal pH and cures BV, Yeast infections, and treats vaginal odor. The results I had were nothing short of miraculous, especially since I had tried everything on the market. It's a highly concentrated blend of vaginal probiotics, and is 100% natural. You can google it and buy it online or through Amazon. If you get repeat infections, please give this awesome stuff a try! Good luck ladies!
Also look into vulvodynia, pelvic floor muscle dysfunction.
Daily discharge is normal for me - but it sounds like your problem is out of the norm... not to mention that you note itchiness and redness. That is definitely not normal.
Have you been checked out for chronic candidiasis? Actually - I doubt regular doctors would investigate that sort of thing. Look it up on the internet and see what you think... perhaps you have other symptoms that are related? Probiotics might be worth checking out, if you haven't done that already.
