Thus I suspect your rectal symptoms are totally unrelated to your possible chlamydial infection and are likely due to something else- hemorrhoids being a possibility,
yeast infection being another. The anal rash you report makes
yeast a somewhat more likely possibility.
I hope these comments help. To be honest, the evaluations and information you have reported, if not mis-understood by you, suggest that the folks who evaluated you were not sure of what was going on.
