Hi there I have been really stressed the last few days just found out my mum has cancer and just generally wound up. I have been getting these sharp stabbing pains in the chest to the right side they come on quite sharply and disappear as quickly as they came. I also have had a lot of reflux. I keep on thinking the worst and thinking its a heart attack but the pain does not go anywhere else.
I'm no medical expert, but I had a very similar problem when my dad was diagnosed with Emphysema. I had it checked out (as you really should too), it turned out to be an ulcer caused by stress.
Go to your GP as soon as you can. As I say, I have no medical training but I just wanted to give you my personal experience.
