My 9 year old son had angioplasty on his right kidney 3 weeks ago. He has had severe pain in his groin and hip area since and is unable to walk. He has been back into hospital twice and all tests have proved inconclusive other than finding a pseudoaneurysm that has now sealed and would not have caused the pain he is suffering. The doctors appear to be baffled and have even suggested that the procedure was not at fault or that he is faking it. He is in agony and it is heartbreaking. Has anyone else experienced this, and if so how long did it last or what treatment did you receive.
