Sorry if you've answered this elsewhere... Have you done parasite cleansing yet? Colon cleansing?
You may or may not have two or three different problems. (The usual "I am not a doctor" stuff applies.) The pains at the bottom of your rib cage... since you've done flushes, you're probably well versed in Epsom salt. Drink a glass when you experience these pains. In twenty or so minutes, your pain will probably go away.
You could also try castor oil packs.
If you're having real heart issues, you might want to check the heart forum instead.
You might also want to check out the possibility of hiatal hernia. A chiropractor could probably give you a good work over to detect heart issues, hiatal hernia, pinched nerves, spine alignment problems, etc.
