After feeling pain n my upper left chest i often have a period of loose bowel movements.....i have been diagnosed with angina.?

This could be angina: Angina can manifest itself in many forms depending on the patient. Classically it is a squeezing pressure which can radiate into the neck, jaw, shoulders, or arms. It is frequently associated with shortness of breath. However, some describe only mild aches, stabbing, burning. Or even no pain at all. The associated symptoms can include diarrhea, nausea, vomiting, etc. You need to see your dr.
