never had any heart tests or problems. been very fatigued for a while now. all blood tests are normal. i yawn alot at times.get cold and sweaty and dizzy sometimes with hard exertion. also have a cloudy feeling in my head alot. only thing that releives this is running. was wondering if i have a heart or circulation problem.

I would say that if it's heart related running would not relieve the symptoms.

I would definately get your heart checked. Yawning can mean that you are not getting enough oxygen. And try getting your sugar cheked. The real one though. Its overnight fast then you go in get your blood tested THEN you drink the gunk they give you and then the test your blood every
hour.
That can cost cold sweats dizziness etc.

Lots of yawning can indicate chronic hyperventilation. Just check the web for the symptoms...

One possibility could be Asthma and allergies.
