It is important to consult a doctor if your treatments for vaginitis are not working, especially if you have already tried multiple medications without success. It is possible that the conventional treatments for yeast infections may not be effective in your case, or that your symptoms are being caused by something other than a yeast infection. A doctor will be able to provide a proper diagnosis and recommend the appropriate treatment to address your specific condition. Delaying seeking medical attention could prolong your discomfort and delay the resolution of your symptoms.
