I am suffering from mild pain in my urinary tract. When i take on bed sleep then its ok but when i make any work standing and sitting then i feel pain. Urine is not as usual. Sometime i make to go to urination but i would become pain and few drops of urine come only. At same time there is some swelling in my private part when i touch. Sometime its frequency increses. Please give proper medication and diet regarding this. Is this a microorganism infection or some other problem.
