I have been having problems breathing for the last 2 weeks but over the past 3 days its been getting worse.
I have a feeling of heavy pressure on my chest and I find it hard to take in a breath - the heavy feeling is always there and it feels like my chest is being crushed.
I have a slight cough and its a dry cough and not constant.
I went to the doctors yesterday and they referred me to hospital - i had a chest X ray, an ECG, blood tests which checked for anaemia, thyroid, blood clots, oxygen levels and something else, blood pressure and pulse taken.
Everything came back totally normal
But I still can't breathe and this pressure on my chest is driving me nuts! I also have a slight strange pressure sensation on my forehead.
The doctor said oh its probably just stress 
I haven't done anything different lately, no more stress than usual!
I have tried relaxing, taking some deep breaths and just switching off, tried not to think about it etc and nothing is working - i still have this awful pressure on my chest.
What else can I do? Do i go back to the doctor and demand they refer me to a specialist? Anyone else experienced something similar?
