I had chlamydia about a month ago. I was on the medication and got re-tested and test came back negative. But I have been getting a sore throat and my tongue has been sore. I was never tested for oral chlamydia because it had never crossed my mind. I realize it could also be allergies and i could be over thinking this but i just want to be careful. Since i was on Doxycycline could it have cured oral chlamydia if i did have it?
