Question: The corners of my lips, the roof of my mouth, and my anus are itching very badly. The effected areas of my lips and roof of my mouth seem to be covered in hundreds of tiny bumps? Please help. This happens to me maybe once a year. Could this be an std called Trichonomiasis?

I tried taking pictures but the bumps are so small that you can't really see them in a picture, but I feel them with my tongue. I'm not taking any medications right now. I've had this problem a few times before, over the past few years. It usually goes away in a few days (4-5). I've done a lot of research on the internet about possible connections to an std and trich is the only thing that sounds close. Seven years ago I traveled to Mexico, while I was there I had sex with a women, about 3 weeks later I was back home. Soon after I had some pain during urination, and the next day I had itching in my anus. I went to the doctor to get tested for everything, I had never heard of trich so I didn't ask them to test me for it. All the other tests came back negative. All the symptoms went away. A few months or even a year later every once in a great while I would feel an itch inside the tip of my penis, but it would go away immediatly. I've since been back to the doctor several times, still with negative test results. Over this time I feel my urethra (where urine comes out) has gotten bigger, and so has my anus. I'm very frustrated because I can't find the answer. The last doctor I saw I asked specifically if he could test me for trich, but he says there is no way to test for it in men. What should I do? The last doctor also did a lot of blood work and found nothing. Maybe they are just not looking for the right thing?

Thank you Dr. Albana I will take your list of tests to my doctor. Umm, how do I go about giving a stool sample to my doctor?
