I am six weeks since testing positive and still suffering bouts of short breath. In fact the other day I believed I had been reinfected. But it comes and goes. I have had to adjust my bed so I don't sleep flat. And started breathing exercises. I am walking about 5000 to 8000 steps a a day (walking the dogs). A mistake I made early in my recovery was thinking I was well and hammering the home gym. I am considering buying a spirometer maybe from here . Other than that I think will have to go back to the doctor for a checkup. Will post updates.
