Hi Thank you for asking HCM. I have gone through your query. If you have signs of urinary infection then better to avoid sex for some days as it can irritate or worsen the condition. Get a urine routine examination. If there is signs of infection then antibiotics might be required. I usually advise antibiotics like norfloxacin empirically and send urine for culture and change antibiotic if necessary after culture report. You can take barley water or cranberry juice which helps to alkalize urine and relieve symptoms like burning and infection. Hope this may help you Let me know if anything not clear. Thanks.
