I went to my doc last year complaining of intermittent shortness of breath and he listened to my breathing,
and did a echo
and an ekg, all were normal. Said it was most likely anxiety as it comes
and goes randomly.
--QUESTION--
I just went cycling and only did one mile (one direction). It was uphill, not too steep but still was a long 1 mile uphill stretch. I am not in prime cycling shape as I have not ridden almost all year. About 1/2 way there I felt like I was going to die!
