You did not specify your age; but there a anumber of things in the chest area
that can cause these problems. Above all see a doctor soon and have an ekg
run. Chest pain is nothing to put off even if only for your peace of mind.
Calcium, as your friend said does build up in the blood supply and joints, arteries, heart, liver (kidney stones), etc. I used to drink a quart of milk a day but what I learned about the milk made me stop cold. I have keep a log on calcium, milk and heart problems. If you want a copy via email just email
