I was assaulted at work by a resident with mr. He flipped me backwards over an island in the kitchen. I have been being treated for back injury. I was having severe abdominal pain and back pain and had to go to the emergency room. They said I had blood in my urine. I have since gone to a eurologist and bladder cancer was ruled out. I have a cat scan scheduled with the contrast die. I was just recently told by a friend that the bruised kidney could have been a result from being thrown against the counter and that the pain in my back, from may thru now, January may not have been back pain put pain from the kidney. Is this true and is it something I should be concerned about.? I no longer have blood in the urine but still get pain in the back and lower abdomen and right under my rib cage?
