Sometime I feel inflammation while urinating or after urination and urge to urinate more, also lower abdomen feels heavy from the past 2 years. I drink more than 3 litres of water in a day and had consulted many doctors for this also lost some weight .my urine tests are all normal, in the ultrasound it says urinary bladder is distended. Wall is mildly thickened. E/o mobile internal echoes seen within. Also I am experiencing back pain, so should I consult orthopedic doctor?
