I am 62, have COPD and much shortness of breath much of the time. I got a cold about 10 days ago. Now I have a fever of 101,feel really rough, and have been coughing up what I consider large amounts of very thick , yellow to green junk, reminding me of pus. I am wondering if this could be pneumonia now. Also, my blood sugars are in the 200's and 300's. I am also diabetic.
