Can Fibromyalgia cause breathing problems that are best described as tightness of lower chest and stomach that won't expand enough to let the lungs take in air. A feeling of suffocation at times but not always. It depends on different ways I do things and I just can't get a good breath. I have had heart and lung tests done and everything reads normal on all other counts. I also feel VERYangry most of the time and it seems the pain is getting worse almost by the day. I am almost 70 and in good health aside from this. Also can Fibro be fatal ? thanks.View Thread
