I have the sensation that the heart is growing huge, left chest harden, which might be side effect of asthma medicine years ago. help?

Have you: Had a physical and talked to your doctor about this? Usually a really large heart can be felt. It would not be caused from asthma meds. If you had a really large heart you would have other symptoms too and it does not sound like you do. A hard left chest is probably muscular

See doc: A sensation of discomfort in the area of your heart need to be checked out. This may be a warning sign of a blood flow issue.
