I am 56 yr old male 6'3" 210 lbs . I work out an hour and a half 3 to 4 times a week and have done so for the last 25 yrs. I take no medications except an antacid on occasion for heart burn. Other than that I have been in excellent health with no past health issues other than some heart palpitations which I had checked out and was fine. I recently moved to Colorado Springs 4 months ago from N Carolina and started having breathing problems. (shortness of breath) I started noticing it more at night and sometimes during the day. I dont feel it at all during my exercise routines, walking or sometimes running, other than normal breathing patterns. I was at first thinking it was just the altitude change. I went to the emergency room about a month ago and they did an ekg, chest xray, blood work and everything came back normal. The doc said there was nothing wrong and sent me on my way. I still have the same symptoms even when Im sitting sometimes, they come and go from day to day. I am somewhat concerned and reading different posts thinking it might be something worse that was overlooked. Do you have any suggestions on what my next step should be? Thanks, and God Bless you all and your help for others.
