I caught my wife s chest cold 4 days ago. The first day was a runny nose, clear and watery. The next day was a mild fever. The third day the fever and runny nose were gone, but had a cough. The cough was mostly gone by the end of the third day, however, I developed shortness of breath and lower back pain. That has persisted to today, the 4th day. Shortness of breath only happens if I move, even rolling over in bed. It feels like the back pain is gas, but I m no expert. Are the shortness of breath and lower back pain likely the last symptoms of my cold?
