Hello, I have mild bladder cystitis with right uvj mucosal edema. Then I have then yellow urine and burning urination. And urine re and cs tests are okay. Then doctor gave me flavoxate for muscle spasms and Ciprofloxacin as antibiotics for 10 days. And to drink plenty of water. I am feeling good when I was taking those medicine. But after 1 month with drinking lots of water per day. If I not drinking water for several time urine becomes yellow. And these days when I am urinating I am feel pain in navel. Actually I got injured in navel before this disease is occurred. One of my friend hurt me at my navel. I failed very much pain that night. I have also habit of masturbation. But I do not know why is this disease came to me? But this disease is came to me after I got injured. And now one day I am feeling that pain while I am urinating.
