Constant pain on the left side of my chest?

You could just have a muscle spasm or indigestion. Take something for indigestion, you may have a gas pocket from that. I want to warn you about drinking too much green tea. It could cause kidney stones. This is what happen to my sister. She was drinking too much green tea. Her Dr. told her to stop drinking it. Green tea is good in moderation but not in excess, It has a chemical in it that forms kidney stones. Drink more water or water you tea down more.
