Suggest Treatment For Recurrent Bacterial Vaginosis And Abdominal Cramps

hi i have suffered from recurrent bacterial vaganosis and yeast infections for the past 5 years and seen so many nurses doctors gynecologists and no one has ever been able to help me figure out why or get rid of the problem for good. i havent even found much relief at all, on average i get about 6 bacterial vaganosis infections per year. i have tried everything from eating healthy, lots of fresh fruits and vegetables, less sugar, etc. , i wear cotton underwear, i use unscented soap, a special laundry detergent, always wipe from front to back after going to the bathroom, i clean and dry myself well and on a regular basis, i dont douche, i dont use feminine heigeine products down there, i take 2 multi vitamins a calcium supplement, and 2 vaginal probiotics containing lactobillus per day. my symptoms mainly are an intense burning sensation, a full bladder feeling, i feel like i cant ever empty my bladder even though i go often, sharp stabbing abdominal cramps, and sometimes discharge (different colors) itching and excess sweating in that area. sometimes i have even gone without wearing underwear and my pants arent that tight. i have also been tested a ton for every std on earth and had a vaginal ultrasound tons of wet preps pap smears urine tests and special tests that cost me thousands of dollars and nothing helped i have only been treated with metronidazole and now clindamycin currently as i type (which metro ocassionally works, sometimes it doesnt but either way my bv comes right back right away). the clindamycin is making me go pee all the time and on top of it i feel no relief what so ever i have been on it for 3 days now. please help me because this is runing my life!!!!
