Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Shortness of breath muscle pain I wish they would define and describe these things, I am confused as to what they really mean.I have a persistent feeling that I need to yawn but cant- is that shortness of breath? Im not wheezing, I just feel tight. I had this a week to 2 weeks ago as well but attributed it to being on prednisone at the time.I have localized muscle pain, is that muscle pain? or does it need to be full body?I had contact with two people recently returned from Beijing 19 days ago. There are a few hundred confirmed cases in my area. ### Response: Needing to yawn is different from feeling like you can't catch your breath. The latter is shortness of breath. Generalized muscle pain is what you should expect with COVID-19, simmer to a flu or some bad colds..
