I am feeling burning sensation and irritation before and after urine pass. I have done urine examination that came normal and I had USG of KUB that was also normal. What could be the reason. kindly suggest I had an appointment with urologist he said it is chronic prostites and  prescribed me doxycycline +l cin 500 + Alfuguard 10 , but after taking these medicines I am not feeling well, suffering from continuous diaheria, nausea and fatigue. I am taking fluids regularly as per the requirement. And all the time I feel dry mouth. I had bsf also that came normal.
