Had chlamydia 2 months ago and got treated. still having epididymitis. urine cultures are negative and no white blood cells. could it be from healing?

Recheck with doctor: Epididymitis this long after chlamydia is unlikely. If you had epididymitis when diagnosed -- i.e. marked tenderness and swelling of a single testicle -- follow up with the doctor who treated you. If it's just vague testicular pain, probably nothing is still wrong and it will fade with time. In any case, if you were treated properly for chlamydia, you can be sure the infection itself is gone.
