Hello Thanks for query . Based on the facts that you have posted nurning urination that you have after having Chlamydia infection treated with antibiotics is most likel to be due ti residual infection of urethra (Urethritis). Get your routine urine test and urine culture done to find out the organisms causing this infection and antibiotics to which they are sensitive to. Take broad spectrum antibiotics like Erythromycin along with urinary antiseptic like Nitrofurantoin twice daily and urine alkalizer thrice daily .Later on switch on to appropriate antibiotics as per culture report. Get the prescription of medicines from your family Physician. Ensure to drink more water .To keep your urine dilute This will help to control dysuria. Since you had Chlamydia possibility of STD has to be ruled out by doing basic blood tests for STD done to be rest assured about acquiring STD. Dr.Patil. Dr.Patil
