Also, since you underwent radiation, this could be a side effewct of that.
My husband was radiated in the
chest area, and has since had much
congestion to teh point of shortness of breath. His cancer is in remission, but teh radiation has effected his heart a bit, and teh mitral valve is leaking. After being treated for bronchitis twice, seeing his oncologist, and cardiologist, nothing showed up except for some fluid in teh lungs.
