I recently completed 3 months of pulmonary rehab and my shortness of breath has gotten much worse. The exercising was very difficult but I forged through it. I was able to do the 6 minute walk test but was short of breath and had to stop every few feet. My dr. only paid attention to me having walked for the 6 minutes but not how I had to keep stopping to catch my breath and kept feeling like I was going to pass out. Very dismissive! Has anyone experienced increased shortness of breath after undergoing pulmonary rehab?
