I came of a horse and landed pretty flat on my back 36hrs ago. First evening felt some sharp tightness on rt back when breathing deep, 24hrs later getting extremely painful spasms across rt back when moving (very difficult to move much at all), very hard to cough (I ve had a cold too, but body is resisting coughing as leads to spasm), and now noticed my chest gurgles when I can get a deep breath. It s tender always, but the spasms are a killer, and now concerned I could be getting fluid on my lungs. ??
