Hello, doctor. My mother has been in the hospital for 3 weeks now she had a 4lb sleen removed. It was swollen and before that she had lost 70 pounds within a 2 year or 3 year span they cannot find any cancer. Hello doctor. The have done every test imaginable and can t find the source. She is at 90lbs and never has lost he appetite this all began 3 years ago,when we discovered sepsis. These Doctor are baffled and their going to release her soon. I m fearful if they can t find the main problem, it will be to late. What else should be done?
