My husband had two knee replacements done 2 ywears ago at the same time. Ever since then he has had trouble with his stomach. He has had countless tests done and was told to eat and avoid certain foods. However, he gets full very fast. He had trouble one day walking and was out of breath. He thought it was his heart. HE WAS RUSHED TO THE HOSPITAL WITH AN ENKARGED COLON IN June 2014 AND WAS given AN NG TUBE TO GET THE COLON DOWN. NOW HE WAS TOLD BY HIS GASTRO Dr. he has an enlarged spleen and is going for more tests. I am worried and disgusted that they haven t come up with any answers. What are your thoughts? He is an 65 year old male that has never smoked or drank. He is also not over weight.
