Why did my chest perceive tight quicker? :o(?

About two hours ago for no reason, my chest started feeling tight, and if I tried to breathe as a rule it would feel worse.

Any ideas what did this?? I haven't get asthma, I am not panicky about anything, I have eat properly today, although I eat a sausage roll earlier that taste strange... can food poisoning cause breathing problems without making you be aware of ill?
Answers:
First sign of panic attack, especially stating your not panicky.

Are your jaws going blue, pain down left shoulder/arm. Severe breathing problems?

Sausage roll? More resembling wind.
I see the inappropriate acai berry advert has turned up again.
