I had an episode of intense chest and jaw pain on Saturday night: sudden onset while lying down, felt like my ribcage was crushing in on itself, with an equivalent pain in my jaw towards my ear. I've had a fair few of them before going back around 15 years but they've lasted only around 10 minutes; this one lasted more like 30 and was staggeringly painful. I nearly called 999 but wimped out, and then it did eventually diminish.
I also have had an issue with air hunger for at least a year, whereby I have to take a huge deep breath a few times a minute most of every day. I've put this down to anxiety, but am mentioning it in case it's connected.
I am nearly 40 and have had atypical bulimia for more than 20 years. These days I only eat and drink anything every other day at most (have had nothing since Friday but will today), and when I do eat, it is always a massive binge lasting a few hours followed by vomiting (obviously I am digesting some stuff as the binge continues, otherwise I would be very much dead)
Called the GP today and just had a telephone appointment. Was told that it couldn't be a heart attack because of my age and lack of risk factors, and couldn't be angina because it only ever happens at rest. I reminded GP about my bulimia and told her that I'd read (on Mumsnet! And also BHF website) about variant/vasospastic/Printzmetal angina or coronary artery spasm/vasospasm and she agreed that that could be relevant and a possibility but still said that a referral to Cardiology would be inappropriate 

Am I worried about nothing? I can't go to A&E 36 hours after the event when I'm feeling fine (apart from standard air hunger, as above). What should I do?
