Hi Doctor, I have white spots at the back of throat. I was diagnosed with Chlamydia two months ago and was prescribed with doxycycline, I completed the 7 days course and again I followed the process after 1 week since I was feeling burning sensation under scrotum. I do not have any other symptoms of Chlamydia, but this throat condition is bothering me. I've been taking zifi 200 mg from last 4 days. The throat doesn't pain. Please suggest me if I should do other STD tests and how to cure this.
