Glad to hear you got diagnosed and under treatment, a guy I worked with was moaning about indegestion for most of a week but no-one was surprised due to the crap he ate, on the friday morning he said something about his left arm aching but unfortunately he only said it to the one bloke that didn't have much of a clue, he said go see a doctor whereas most of us would have just called an ambulance there and then ( we only found out about the arm ache the next week).
He was due to fly out to south africa on the sunday on holiday so didn't want to see a doctor in case it messed his holiday up, trouble is he didn't make sunday morning....... RIP Grunty!
6 months later the manager had similar symptoms, needless to say he was straight on the phone to the docs who got an ambulance sent, a couple of stents and a few months off work and job done (along with millions of tablets on a regular basis).
Trouble is we are all too eager to ignore the clues far too often.
