Since yesterday I've had a pain in the middle of my chest under my ribs, sorry of just under the bit between your boobs. It isn't burning, it's just a sharpish constant pain. I have a lot of stress going on at the moment but presumably it's not that. I've never had it before! Google says maybe acid but it's just come on with no warning all of a sudden. Any experiences? Obviously these things always happen at the weekend. Thank you!
