I live in South Dakota so I'm in the same boat during the Winter months. I used to work out everyday but 4 years ago, i tore both biceps and totator cuffs at the same time. Had surgeries on both arms and was told not to lift weights anymore. With severe asthma and whatever else I am dealing with, I get shortness of breath so easy that walking or taking a shower is exhausting. I still try to be active but i must admit, I fail at it. I hope that my appointment next week with gastrointerology will have answers for me. My Barretts is pretty bad and my hope is that they can improve my airway by taking out some damaged/inflammed tissue. Or maybe my throat has some stenosis due to being intubated so many times. I don't know at this point.
