Been suffering with a dull like pressure/pain across my sturnum and up above my left breast for a couple of days now. It's worse when I lie down. I've been trying to ignore it because I'm on holiday but it keeps chipping away at me... And last night I was begging my husband to phone and ambulance (which he didn't) just so I could get some reassurance. Today it's still here and as ive had jaw pain and left arm pain intermittently I'm now desperate for reassurance. If I'm completely honest the pain isn't excruciating and I would probably be able to deal with it if i was sure it wasn't something sinister. I've had an ECG fairly recent and that was fine but now I really want to go to the local a&e department :-(
