Chest pressure after exercise

[ssla]

I am a 38 year-old female, I work as a fitness trainer and yoga instructor and am in very good physical condition.  I started doing Crossfit (high-intensity aerobic exercise) about 2 months ago.  Today, a couple of minutes after completing a high-intensity workout of rowing, jumping and running, I experienced intense pressure in my chest that took several minutes to go away.  The intensity of the pressure was constant; it didn't change with inhalation or exhalation.  I checked my heart rate and it seemed stable.  I have never had this experience after exercise, so I am a little concerned.  I am in great overall health, my resting heart rate is 45 and I've been told by several doctors in the past that I have a strong, dynamic heart and no observable abnormalities that can be seen on an echocardiogram.

The only issue I have is that my blood pressure tends to run low.  It doesn't usually affect me, but occasionally I get lightheaded when I get up too fast.

Any thoughts on whether I should be concerned about this, or if I should get checked out?

Thank you!

Just to add, you obviously know how important it is to drink plenty of fluids with high exertion workouts. Dehydration can affect your circulatory system and your heart.

With ANY chest pains, it's always worth seeing a Doctor. Even athletes can have problems. I assume you do a warm down at the end of your exercises? and don't just stop and sit down.
