I have a very stubborn dad and will be 71 next month. He has had pneumonia for about 4 weeks (on antibiotics), was 228 and now 202. He has had several x-rays and a CT scan last Thursday, we found out Friday he has something over the pneumonia obstructing the oxygen. He is really hoarse, coughs and sleeps most of the day (was walking 2-3 miles a day). He told me yesterday, he really has to concentrate to walk and it's like~ the words won't come out! I am beyond worried. He is not a smoker, was overweight many years of his life and 6 years ago had gastric surgery. Any information would be great! He has plans of leaving Michigan in 3 days and will not stay for a scope and biopsy.
