I'm having terrible problems with fatigue and shortness of breath. Every breath feels an effort and a very uncomfortable tight feeling in the chest. I don't smoke and barely drink & lead a heathy life. I'm only in my thirties and now try and avoid leaving the house as exercise makes it worse.
So far I had an ECG and ECHO on the heart and they came back clear. In 2 weeks I am having a CT scan of the chest.
What I would really like to know (I'm literally clueless!) is what other tests can I have done?
Should I be measuring the oxygen in my blood somehow? What else can I request from my GP as they aren't helping?
Any help is greatly appreciated.
