I’ve always been underweight, and now I’ve actually gained weight, by supplementing my diet with a Boost very high calorie drink on days I don’t get enough calories. I do have days I’m very fatigued, but I also don’t sleep well, and some days I need to cough a more and others not at all. Some days my chest fills tight and it feels harder to breathe and I feel like there’s stuff in my lungs when I cough, ( I usually have to make myself cough) but I can’t cough anything up. The Dr. I have hasn’t explained anything to me about my condition, what the treatment plan looks like, only to take the medication and that it will make me sick, has never asked about symptoms, and doesn’t like to answer any questions I have.
