Hello Woot. Sometimes I am forced to walk when I don't feel up to it because I have to walk my two dogs. I find that I feel a little better after doing it. Then there are times where I do not want to get up off of the couch (not often) then I use my strtchy armbands to work my arm muscles. I do not like to be listless. Do you own a pulse oxometer to check your oxygen
and heart rate on a regular basis? Is it possible you may need supplimental oxygen? I found that I needed supplimental oxygen before my dr did, she only recognized it because I brought it up. I had tested myself with the pulse ox while I was walking my dogs and found that my oxygen level would drop down to 84. No wonder I was tired and short of breath! I am not implying that you need supplimental oxygen; this is just one avenue to keep an eye. If you do have a pulse ox, have you checked your c02 level with exertion?
