I started showing symptoms about 8 weeks ago, and visited the doctor 6 weeks ago. She treated me with fluconazole twice, and Metronidazole, to no avail. Symptoms did diminish but never fully went away. I'm just finishing up a second round of Metronidazole, and a second culture found a different bacteria. I'm now on my 2nd of 14 days of Sulfamethoxazole, and I'm itchier than ever. My symptoms are itchy and sometimes burning sensations, slight discharge, no odor, and a raw feeling inside. Today I'm noticing anal itchiness as well. I haven't had sex since symptoms began. Could my doctor be misdiagnosing me?
