My question is about my husband. I am not sure when to worry and he wont talk about going to the doctor!  About a week ago, he was working out like he usually does and got real dizzy on the eliptical machine.  Ever since then he has felt a bit different. Yesterday he got winded just running across a parking lot and has had a tight feeling chest ever since working out yesterday.  He has achy legs and not much of an appetite.  Do you think its a bug or does it warrant a doctor visit?  He is overal good health and has maintained a 100 pound weight loss for the past year now.  He works out 3-5 days aweek as well.  Any thoughts?
Listen, chest pan occasionally is not to worry condition, but in your husband case go to chest X-ray done and some blood examination like CBC, thyroid, and also ECG for screening of heretic will surely help you
