I just found out I have a lesion on my spine at the T3-4 region. It is suspected that I have MS. I also have a strong feeling that there is something squeezing or crushing my right lung and sometimes feel like I can't get enough air. Could the lesion be causing this? Last year I had a chest x ray for a respriratory infection, and it showed increased density at the bottom of my right lung. Could this be causing the sensation I'm feeling?
