<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have not had sex in almost 2 years but was having a problem which I thought was yeast infection. Nothing over the counter was working so I went to the doctor and was diagnosed with Trich. Can trich be dormant that long? Also, they gave me metronidazole 2 days ago. Today I noticed there is a discoloration around my rectum. Is this normal?  <response>: Hello, Welcome to Chat Doctor, The history and symptoms suggests me that you are having a fungal infection, but it should be confirmed by physical examination. Dont be embarrassed to show and confirm the diagnosis. The fungus is the normal commensalism of this area which will be kept under control by the helpful organisms, whenever there is a change in environment because of multiple reason this fungus will multiply and produces the symptoms. I would suggest you to follow1. Keep the area Chat Doctor. 2. Topical antifungal cream should be applied.3. Tab Rifleman, 150 mg single dose will help to control the symptoms.4.
