[|Human|] When I was younger I was riding a bike down the hill and ran into some bleachers. I hit the lower  part of my abdominal straight across and Ive been having pains that gets worse and worse now. Doctors tell me that they cant find anything, do you know what it could be?th
[|AI|]  Hi. Thanks for your query. Yes, it is difficult for the Doctors to find out the cause of pain in such cases. In my experience, there is fibrosis or degenerative changes in the muscle groups that has borne the injury in the past. These changes mat be detected on MRI or high resolution ultrasonography. IT is not surly picked up every time. I would advise you to see a Surgeon for clinical examination and few investigations like MRI of the affected area with a knowledge of the radiologist who is going to report it. Exploration of the area, removal of the fibrotic tissues help in some of my patients. This is all based on the facts that you have put that Doctors can not find anything.
