My son came to me tonight with many problems. He is 35, 5'10,330lbs.He has had a rash on his leg for some time now. He told me that he has been retaining water also. When he presses down on his leg around the rash, his finger leaves a deep indenture. It take about 6 seconds or so to return to normal. This does not look good. He also told me that he has been having a little difficulty in his breathing. He also told me that when he urinates he feels like his bladder is not fully empty. He also told me that he has been spitting up blood. His doctors app. Is not until Aug.6,2013. He wants to wait until then to do something. I am trying to talk him into going to the emergency room. Please help me to understand what might be going on with his health? What does it sound like to you? Is this a major health problem?
