Hello rellie36. Thanks for visiting healthcaremagic.com. I am unsure of your sex and your age and the actual location of your pain, as you do not mention these. However, this type of pain is a concern for heart disease
. A lot of patients who end up with heart disease complain of a pain that is "like an elephant sitting on my chest".
It appears that your pain is similar to this if there is "someone standing on your chest". I would advise that you go to your nearest emergency room for evaluation.
Be well, Dr. Kimberly
