Guys, I think it would be a good idea if we stopped giving out medical advice on this site. I appreciate that you've all had different experiences over the years and have 'lived' to tell the tale.
However, if someone has pains in their chest, dont tell them that its definitely trapped wind, it could be .... anything. There are a multitude of signs and symptoms for someone who is having a heart attack, and there are varying degrees of attack, some a lot more intense than others, but
all need to be checked by a qualified doctor.
If someone has an ongoing complaint as has been mentioned earlier and has been seen several times already by qualified personnel you have no need to worry about a heart attack but you should go and get your condition sorted once and for all..... for your own peace of mind.
