From past 3 weeks I have problem in urination. The quantity of urine I pass is less. I also had pain and heaviness in lower abdomen,groin area,back,buttock,thighs and even legs. Now i am also having little irritation and mild pain in vagina while sitting. Also I am having light periods from past 2 months. I did urine culture and pus cells are 2-3. Also USG of lower abdomen doesn't show any abnormalities. I don't understand what the problem is I am really tensioned
