Did the doctor do any lab tests top determine the cause of your symptoms? What caused you to choose this solution to your problem? I'm not sure if what is causing the issue you are experiencing, but a product by the name of betadine is an antifungal and antibacterial to which fungi and bacteria cannot develop resistance. However, there are instances in which some may experience a reaction to the product. A wiki article going on depth regarding betadine is found here: https://en.m.wikipedia.org/wiki/Povidone-iodine Another helpful medicinal item would be Manuka honey. It's used in hospitals for MRSA. It's expensive but it's definitely medicinal and there are numerous online studies indicating it's efficacy. However, I must reemphasize that your description of the issue from which you suffer is vague. Therefore I must press you to seek a diagnosis or research further into the problem which besets you in order to properly advise. I hope you will find the answer you need. I feel for you. : (
