Hi Sue. I will be seeing the infectious disease doctor on Monday so will find out about treatment. My pulmonary doctor said that if it were her she would start treatment. I am having my Hill-rom vest delivered Tuesday. I have not been feeling well for the past week. Have that feeling of pneumonia in my chest. Could you explain what an flair up feels like. Just wondering if that is what’s going on with me. Also I have really dry cotton mouth and I am constantly drinking water that I boil. Have you had that problem? We put a water filtration and bacteria on our house water system. I have a hot tub however I have not been in it in the last 5 years. Probably have only used it 10 times in 15 years. Doctor said I probably got it years ago whenI used it. I have always enjoyed my hot showers too. Do we ever really know how we got this? Husband says we will never know so stop trying.
