My husband is 49, 6'4", very healthy-fit. He has been having lung restriction and unusual heart beat feelings. The heart doctor has found an occassional extra heart beat that he is not worried about. The lung doctor has tested his lungs for asthma and says his lungs look great. He quickly runs out of breath doing fairly light exercise, like steps. This is VERY unusual. However, when he does the treadmill at the doctor, he seems to do well. Also, he is experiencing small bruises on his eyelids that come and go, carpal tunnel, and erectile dysfunction. Any connections? The doctors are still testing, but hoping you can provide some insight.
