I have been a jogger/runner and bike rider for years, since college in the late 60's and early 70's right on through to the present......a couple of years ago I joined the local Y and added weight training to my routine......about a year ago I noticed that it was becoming harder and harder to run......I finally got to a point where it was torture to run.....I would be gasping for breathe after a few steps but by virtue of absolute dogged persistence, I kept going.......I used to be able to run 6 to 9 miles with only a moderate amount of effort and at a good pace.......I ran all the 5 and 10 Ks in the area and usually finished at least in the middle of the pack.......now I jog very slowly for 4 miles, as I said, gasping for breathe for most of the way......finally I went to a doctor who examined me and gave me an ekg.....everything looked normal.......but the running problems continued.....so I went to see a cardiologist....he gave me a echo which was normal and then a stress test....with the nuclear injections......the whole 9 yards......what he discovered was a mild myocarditis....at least that is what appears on my insurance form......he is not sure why I have this........but from what I have read on the internet it could be virus related, in which case there is no treatment and it could become worse.....I wondering if anyone has anything encouraging to say because at this point I am very bummed.....I know that alot of people have things alot worse but this has been a bad year.....my wife was diagnosed with {*filter*} cancer and I was supposed to be the ROCK which I still try to be but it's getting very hard....... so is it true that there is no treatment for this stuff.....should I find another doctor???? for a second opinion or someone who will try "something" steroids or antibiotics......???????
