PH Balance

I really hate this... My doctor doesn't have really any answers for me I've taken STD tests... all have came back negative luckily... or at least the ones He has taken ( the normal HIV, Clamidia, Gonarea, Syphilis, and all) and has cultured my symptoms... and I know part of it is through the years of taking antibiotic for sinus infections... but I feel discomfort first getting regular yeast infections then they would get so bad it would go to Bacterial... and recently got a gel from gyno for bacterial I go back in and say we will culture it this time... and gave me a plain prescription for yeast infection... culture comes back fine... and I still have pinching feeling with and out peeing... so said azo... going to take my second today because I forgoy to take one Saturday and took first in friday... but really is there anything to do for reoccuring yeast or bacterial infections... I am so scared to try anything with my husband bc it has caused swelling so intercourse hurts.... and stuff.... just not sure what to do or think anymore. 😔
