<s>[INST] hi i guess i have a chlamydia since my doctor gave me antibiotics (norfloxicin)for 7 days. i have finished taking 5 days ago. but i still have penile discharge, pain while urinating and pain when having erection. pain goes away when in flaccid state. the earliest  appointment i got with the doc is on friday. i worry a lot. pls help [/INST] Hi and. Thank you for your query. It sounds like STD and this must be ruled out first, You should do urethral swab test to investigate the exact causative agent.  It can be viral or bacterial infection. If there is discharge, pain while urinating or pain in testicles it can be bacterial STD. Most common viruses are herpes, HPV and molluscan contagious. Before tests, visit your GP or pharmacist and ask for some antibacterial treatment. Wish you good health. </s>
