I have chlamydia but never showed symptoms, now i am showing one symptom (burning urination) during treatment (1 day left), is this normal?

Antibiotics: It is most likely the burning sensation you are feeling is a side effect of the antibiotics than from chlamydia.

One possible reason: Is that yeast infections can develop while on antibiotics. A clumpy (cottage cheese- like), white, non- odorous discharge associated w itching, burning, swelling or redness can be due to yeast infections.

Dysuria: Dysuria is the feeling of pain, burning, or discomfort upon urination. Although dysuria frequently indicates the presence of a urinary tract infection (UTI), it can have a variety of causes. Dysuria should always trigger a visit to a health-care professional for evaluation and diagnosis. http://www.emedicinehealth.com/dysuria/article_em.htm#dysuria_overview
